There are two things you can play with. One is the UDMA burst mode on the
chip which should be getting set, the other is PCI latencies (which the
BIOS should have set up but you can play with)

Probably a good idea

Next things to try are

1. edit drivers/ata/pata_pdc202xx_old.c
after the line

iowrite8(burst | 0x01, bmdma + 0x1f);
add

printk(KERN_ERR "BURST was %02X\n", burst);

build/install/boot that kernel and see what it says.

The second (sledgehammer) approach would be to use setpci to set the
LATENCY_TIMER value on the pdc202xx_old and network card differently.
