framebuffer/grub boot options
 
i've recently upgraded my kernel to 2.6.9 from 2.4.26 and now when i boot i get an invalid framebuffer value error. with the old kernel i had 'vga=791' added to my grub.conf which gave a FB at 1024x768 with 16bit colour.
what are the correct options for the 2.6 kernel, or don't i need to use the vga= option anymore?

cheers!

Try hexadecimal notation:

791=0x317
Code:
    | 640x480  800x600  1024x768 1280x1024
----+-------------------------------------
256 |  0x301    0x303    0x305    0x307 
32k |  0x310    0x313    0x316    0x319 
64k |  0x311    0x314    0x317    0x31A 
16M |  0x312    0x315    0x318    0x31B

Are you using vesafb or vesafb-tng in the kernel options?

If tng, you need to specify a video= option instead of a vga= one - this caught me out recently too!

with the old kernel i was using radeonfb but now lsmod shows vesafb(i think, i don't have my laptop w/ me right now, but i know it's not radeonfb anymore)

i'll try them both later on 2night.
cheers!

unfortunatly none of those suggestions worked :( i still get 1024x768 with only 16colours.
when configuring the kernel what's the syntax for the 'vesa default mode'? when i added mine i was so tired i forgot what the default looked like(literally seconds after i backspaced it) :) so i added something ramdom like 1024x768@60
also can i use radeonfb again??
