Thanks Kevin,

That helped confirm my suspicions.  Here's my output with
the intel driver on my Intel 82865G:

Same computer using the vesa driver:

I was running at a higher resolution using the intel driver,
but it's nearly 10x slower.  Is this expected from this
driver?  Until very recently it was hanging my system,
so maybe it's still not mature?

Thanks,
