you do realize that this console switch can be automated?

for instance, i put  vidcontrol -s 1 < /dev/ttyv0  in rc.suspend just before
the logger line and  vidcontrol -s 9 < /dev/ttyv0  (12 in your case) into
rc.resume, also before the logger line.

this workaround has been mentioned quite a few times on the list.

keep in mind though that rc.suspend and rc.resume were only recently made
ready for acpi, so if you are using acpi instead of apm, you might have
to update to -current. for ibm thinkpads, this is generally a good idea
anyway, at least if you use acpi.

cheers, t.
