troubleshooting guide

Is there a troubleshooting guide available for xserver setup?

I run Xati, but it's slow (I can watch redraws happen). I suspects it's
due to me using vesafb and not radeonfb, since the latter is not
compiled by default in later fedora development kernel builds.

This is on a thinkpad T30.

dmesg;

vesafb: framebuffer at 0xe8000000, mapped to 0x32814000, size 16320k
vesafb: mode is 1400x1050x16, linelength=2800, pages=4
vesafb: protected mode interface info at c000:5701
vesafb: scrolling: redraw
vesafb: directcolor: size=0:5:6:5, shift=0:11:5:0
fb0: VESA VGA frame buffer device

Xati says;

Using ATI card: ATI Radeon RV200 LW at pci:0000:01:00.0
Screen: 16/16 depth/bpp

/etc/grub.conf;

[...] video=vesa:ywrap,mtrr vga=834

Will it run faster if I use radeonfb instead of vesafb? I tried running
without any fb setup, but then I only get a black screen.

Any hints and clues greatly appreciated.
