Removing the quirks from my machine's model/type code (7668) from:

/usr/share/hal/fdi/information/10freedesktop/20-video-quirk-pm-lenovo.fdi

fixed the problem for 2.6.26, but apparently it did not help for
2.6.27-rc1+ (Linus's public git tree as of this morning).  With
2.6.27-rc1+, the screen stayed dark upon resume, without any backlight
or the blinking text mode cursor.

I have not checked to see if removing the quirk settings will break
suspend-resume on 2.6.25 kernels.  Hopefully whatever we need to do to
configure userspace will settle down...
