You will have to reinvent about this number of lines:
j@uriah 99% pwd
/usr/othersrc/XFree86/xc/programs/Xserver/hw/xfree86
j@uriah 100% find accel {bdm2,hga2,mono,vga256}/drivers -type f \
-name '*.[ch]' | xargs wc -l | \
awk '{count += $1;} END {printf "Total: %d lines.\n", count}'
Total: 334924 lines.
... for getting the same amount of hardware supported as XFree86(tm)
does support by now. Maybe i've forgotten something, but this should
give you a rough estimation about the hardware-dependent code.
