console resolution, ati [SOLVED]

bought a new graphicscard, ati radeon x800 gto, and now I can't set the resolution in console.

when I use vesafb-tng with 1024x768 it only shows scattered bootmessages around the screen at 640x480 (or something) and freezes.
this worked fine with my nvidiacard

If I use vesafb vga = 791 or vga = 0x318 still displays 640x480
dmesg show nothing about vesafb or something like that

with radeonfb I can't even boot, 'cause it stops when radeonfb looking for a second screen that don't exist, but still in 640x480.

when I run livecd everything works fine in 1024x768.
I have tried the kernel config file and the bootparameters from livecd but still I can't get 1024x768 without the livecd.

running kernel 2.6.16-gentoo-r2
same problem whether I use lilo or grub

thanks for help

Hi again

I have 3 ati systems
acer 5024WMLi laptop with PCI Express X700
XP3200 system with AIW 9800 SE
XP2800 system with AIW 7200

All these work with vesafb, mixed results with vesafb-tng and shit with radeonfb.

Some modes do not work with all cards - have you tried with other colour depths e.g. vga=792(32 bit colour this works for me on all of them)
vga=795 (1280x1024 32 bit) on the 9800
vga=792 (1024x768 32 bit) on the laptop with 1280x800 lcd panel

Other problems occur when I have had both vesa and radeon enabled in kernel

ok finally got it working..

wiped kernel-config file and configured a new one and now vesafb loads fine...
guess I missed something the other times..

thanks anyway
