Xconfig not taking

[Philip Prindeville <philipp_subx redfish-solutions com>]

Well, I imaged an installer DVD with the following in my ks.cfg file:

# X Window System configuration information
xconfig --driver "radeon" --videoram 32768 --resolution 1400x1050 --depth 24 --startxonboot --defaultdesktop gnome
# System monitor
monitor --noprobe --monitor "LCD Panel 1400x1050"


but instead I'm seeing in /root/anaconda-ks.cfg:

xconfig --driver "radeon" --videoram 32768 --resolution 800x600 --depth 24 --startxonboot  --defaultdesktop gnome
monitor --hsync 31.5-90 --vsync 59-75

no idea why.  This is on a laptop (a Compaq nc6000).  The rest of the config
seems to be taking just fine.

This is with FC5.

Any ideas?  Oh, minor note...  I have:

cat >>/etc/modprobe.conf <<__EOF__
options radeon allow_r300=1
__EOF__

in my %post script (the chroot'd one)...  Does that need to be done
earlier, as in the %pre script?  I don't even know if the /etc/modprobe.conf
file will be present on the /mnt/sysimage/ filesystem at that point...
