That doesn't say much.  The stability of the 5 V line is probably more
important (or the noise on the ground potential while stronger
currents are flowing) than the absolute value.

I think Bruce once mentioned some brokeness about the Winbonds, but i
eventually forgot what it has been.

I'm too lazy to reboot right now, but i can't find it in a `strings'
running on the BIOS ROM image.  Here's what seems to be the PNP/PCI
menu on this board:

Whatever this might be...  I'm not a PCI expert.
