As usual, the BIOS leaves the chip in a random state on resume, and the
driver isn't going through and carefully resetting everything.

Can you try using 'vbetool post' between the resume and the switch back
to X to see if that makes it work?

Here's a script I used to use:

#
# remember current console, switch to spare console
#
CONSOLE=`fgconsole`
chvt 12
#
# suspend
#
echo mem > /sys/power/state
#
# POST video
#
/usr/sbin/vbetool post
#
# switch back to remembered console
#
chvt $CONSOLE
