Suken, it looks as though you have an ATI adapter in your
machine. ATI represents all of its VESA modes with a flag
set that FreeBSD interprets as meaning the mode is bad.
There is a simple fix for this but you'll need to recompile
your kernel for it to take effect (I do this on my machine).
Apply this patch to /usr/src/sys/i386/isa/vesa.c :

Getting rid of the (V_MODENONVGA) test will allow you to get
VESA modes and the vesa.ko module should load right up for you.
I've been unable to get the SC_PIXEL_MODE kernel configuration
option (check LINT) to work so I can't get it to switch into
800x600 VESA mode on my machine...
Good luck!
Sean
