They finally got the raster VESA modes patch into FreeBSD??? Will it
be in FreeBSD 6.x?

If anyone whats this in FreeBSD 5.x I have a basic script that will
apply that patch. The patch I have might be outdated (someone have a
more current one???) Anyways:

Run this script as root (make sure the patch was applied cleanly):
---------------------
cd /tmp
rm current-vesa_patch.tar.gz
fetch http://www.nbritton.org/uploads/current-vesa_patch.tar.gz
rm -r current-vesa_patch
tar -zxvf current-vesa_patch.tar.gz
cd /usr/src/sys/dev/syscons
patch </tmp/current-vesa_patch/current-syscons.diff
cd /usr/src/usr.sbin/vidcontrol
cp /tmp/current-vesa_patch/current-vidcontrol.1 ./vidcontrol.1
cp /tmp/current-vesa_patch/current-vidcontrol.c ./vidcontrol.c
make && make install && make clean
----------------------

Add this to your kernel file:
---------------------
options VESA
options SC_PIXEL_MODE
---------------------
and then recompile your kernel.

Add this to your /etc/rc.conf file:
----------------------
allscreens_flags="MODE_279"
----------------------
and then reboot. It will complain something about vidcontrol and your
mouse, just ignore it.


The patch can also do higher modes like MODE_282 (1280x1024) etc. if
you update your system via cvsup you will have to run the script again
because cvsup will over write the files.

This patch also fixes the problems with older ATI cards that don't
have a real VESA BIOS.
