ugh!!!
and the vga bios is running at 16 bit mode? and its slow with all its
timing loops and other stuff.
which graphic cards are in the other 1%?
hah! this is another argument for ogp. i have to start studying fpgas
now. i need an open graphics card that boots at a fraction of the
speed of current cards and boots straight into framebuffer mode.

things i hate about my linux pc:
1. it takes more than a second to boot up
2. keeps asking about filenames and directories
3. does not remember what i was working on yesterday
4. does not remember all the changes i have ever made
5.cannot figure out necessary settings by itself
