8 Don't know the specifics of your hardware but I use vesa framebuffer
9 which works fine for me (stationary pc, radeon 3870). However, for some
10 reason, the radeon cards I have (all rv600+) do not seem to support the
11 standard vga modes; I had to use a tool (vbetest from package lrmi) to
12 find out the number to put into the kernel command line. I use vga=804
13 to achieve 1280x1024@24. Don't know if this will help but it can
14 probably (don't know for sure) find the supported modes...
