That's great news Gary, good hunting.

I read that forum post, which did look worth trying.  Whether it's a 
BIOS bug or just something to watch out for I don't know, but it seems 
to be a trap for the unwary; so many BIOS settings are poorly explained.

Those guys were losing 768MB or more, but had plenty to spare.  You?

I'm still running an older Xorg here, so had no idea about any default 
10 minute blanktime.  I'll remember that ..
