Well... I don't know. It seem to work, so it's probably an acceptable
workaround, but I'd like to find out what's wrong with doing it in blank
precisely (that is what is the bug in XFree or in the kernel VT), since it's
shared by many X drivers, I don't suppose it's a bug in them.
I'll try to find time to toy with this, but I may not have any until after
OLS though....
Ben.
