This problems is not exclusive to slow boxes. Just over a year ago I= installed 3.4 on a new Dell with a 500MHz PIII and when I got PPP going I= saw a mountain of the sio0 overflows. Bit of hunting around found the= advice to turn on DMA for the IDE controller and turn off USB in the BIOS.= This helped a lot but didn't get rid of them completely, just reduced them= to the point where it was possible to ignore them. Just for a test I= installed a second serial port and tried using that, made no difference.
