Yes, the version from 2.6.8-rc1 works, the one from 2.6.8-rc2 does not.
It looks like 2.6.8-rc1 actually had a newer version of this file.

This one works:

LK1.2.0-2.6 (Roger Luethi)
- Massive clean-up
- Rewrite PHY, media handling (remove options, full_duplex, backoff)
- Fix Tx engine race for good

This one does not:

LK1.1.19 (Roger Luethi)
- Increase Tx threshold for unspecified errors

Relevant options:

CONFIG_VIA_RHINE=m
CONFIG_VIA_RHINE_MMIO=y
