    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    It looks like 2.6.8-rc1 actually had a newer version of this file.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
