Bug Description
DESCRIPTION
I can't use 1024x768(vga=792).
The best I can get is 640x480(I'm not sure but it looks like it is) when I use vga=normal.
Important: this problem is only TTY related and X and KDE do work in all videomodes up to 1280x1024.

SYSTEM
Distro: Ubuntu 8.10 Alpha 5, 64-bit, CD
CPU: AMD Athlon 64
Video: NVIDIA GeForce 7600 GT
Monitor: Samsung SyncMaster 740 BF (LCD, native resolution: 1280x1024)
Chipset: nForce 570
LOGS
1. kernel_normal.log (vga=normal, works fine but it's only 640x480).
2. kernel_792.log (vga=792, it fails to set 1024x768, black screen).
3. kernel_795.log (vga=795, it fails to set 1280x1024, fallback to 640x480).
4. lspci-vvnn.log
HISTORY OF THE BUG
I switched from Hardy to Intrepid Alpha 5 and I noticed that 1024x768 stopped to work at all(black screen). I don't know whether this problem was introduced in 2.6.27 kernel but I know that my Hardy uses 2.6.24 kernel and 1024x768 works fine there.
MISC
There is another bug that I have with Hardy. It might be related.

I'm the bug reporter of this bug.
I installed the 2.6.26-1-rt kernel and I was having the same problem(black screen) as I have with the latest kernel. It makes me think the kernel got broken between 2.6.24.20 and 2.6.26-1-rt or it's not kernel related.
