I have a Thinkpad T61 with the following configuration:

- Intel GMA X3100 graphics
- Intel 3945 wireless
- 15" screen w/ 1280x800 resolution

I've encountered all of the bugs mentioned in the original report, and some more.

1. If you leave the SATA controller in AHCI mode, Gutsy won't see the CD/DVD drive at all.

2. I installed my system from Gutsy Tribe 3 Alternative CD (because I didn't figure out the SATA fix), and in the middle of the install process the screen went blank.  I think this happened when the xresprobe package got installed.  I had to finish the installation by hand (essentially pressing Enter whenever the CD spun down).

3. I think the font issue is DPI related, as I didn't notice anything on my 100 dpi laptop panel.

4. s2ram -a1 does the equivalent of passing acpi_sleep=s3_bios on the kernel's command line, by echoing 1 to /proc/sys/kernel/acpi_video_flags prior to suspending.   This is needed to get the backlight back on after a resume. The loss of the second CPU is caused by a kernel panic on resume:

platonas kernel: [ 3022.064000] Kernel panic - not syncing: Attempted to kill the idle task!

The same panic occurs if I try suspend to disk, but during suspend rather than resume.

Booting with maxcpus=1 gets rid of the panic, but introduces delays of indeterminate length in the suspend/resume process.  I get the blank screen with "inu" written on it, and nothing happens for several minutes.  Then I start tapping CapsLock furiously and the computer wakes up and finishes resuming in several more seconds.

5. Sound doesn't work out of the box: ALSA needs three patches mentioned in http://www.thinkwiki.org/wiki/AD1984.  There's an existing bug about this in launchpad: https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/122560

6. Wireless works if you configure it manually.  There's an existing bug in launchpad about Network Manager being unable to connect to an open access point: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/121439

7. The intel driver enables TV out defined as Xinerama screen 0, this causes gdm and gnome-panel to ignore the area outside the top-left 1024x768: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/123170

8. thinkpad_acpi module is not loaded by default, as a result Fn-F5 doesn't toggle Bluetooth.

9. Once the thinkpad_acpi module is loaded, Bluetooth works, but the LED stays off giving no indication whether you have Bluetooth enabled or not.  Interestingly, the Bluetooth LED stays on during boot time, but goes off as soon as I log in.

10. Screen brightness controls don't work sanely.  https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/123548, https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/123548 and probably more.

11. After a while a message about IRQ 23 being disabled appears in syslog.  Two USB ports on the right appear to stop working: https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/126369

12. Once during boot time there was a 30 second pause after which usplash disappeared and I got a scary kernel message about an exception on ata1.00.  I had SATA set to AHCI in the BIOS at that time.

13. The fingerprint scanner doesn't work out of the box: https://bugs.launchpad.net/ubuntu/+bug/117654
