Keyboard, mouse and bios settings lost after update

[NKJensen]

Ubuntu 8.10-alpha 3 with updates.

I did at fresh install of intrepid 8.10 alpha 3 i386 on a IBM Thinkpad T20. Fixed a X-server problem using the new rescue panel. Ran update manager and installed everything.

Next boot: Black screen (again). Booted with rescue, fixed the X-server again, updated from the net and rebooted.

Now bios settings are gone (the bios does not show the familiar "F1 for help, F12 for boot menu" below the IBM logo anymore. Worse, the mouse is completely dead (cursor is locked on the logon screen), and only special keys such as ctrl-alt-F1, ctrl-alt-del and "Caps Lock" work. I can not enter a username for login. Kernel is shown in GRUB as: intrepid-2.6-26-5-generic

I've tried to use the intrepid-2.6-26-4-generic and the rescue - neither works now.

I ran the memory test which showed a lot of errors.

I did disconnect the PC for some time (from the AC adapter) and now the bios-menu is back. The screen still goes black after reboot with the newest kernel (-5 as above), and the PC is locked up so hard that not even CAPS LOCK works any more. Holding down the power button for some seconds stops the PC. Trying the newest kernel rescue mode. Recovery menu: "xfix". Then "resume". Log on screen appears, no sound signal. Keys are dead again. Mouse is stuck.
