I tend to use RedHat, but I'll look for the issue anyway.

Promising news!

Good point, and one to consider.  I'm not sure how much effect this
will have on my home use machine - if I can cut the cost of the
upgrade to mobo+video+RAM, I moght be able to fill the board with RAM
and cut the amount of swapping enough to make it reasonable.

I'm clueless about SATA - does it allow hot-swapping?
