I would like to notice that the changes in 2.4.18-pre7 to the
tulip eth driver are apparently causing absymal performance drops
on my version of this card. Apparently the performance is dropping
from the expected 10MB/s to about 10kB/s. The only special
thing about the configuration in question is the fact that it's
a direct connection between two hosts. Well, more precisely it's
a cross-over link between my notebook and desktop.

Here is an excerpt from the lspci command:

00:0b.0 Ethernet controller: Digital Equipment Corporation DECchip 21041

        Expansion ROM at cff80000 [disabled] [size=256K]

The motherboard is a SiS735 chip. The card is apparently sharing it's 
interrupt
(which I guess could be a cause of the problem) with nearly anything else
on the system:

Oh well yes I have added the newest version of the i810_audio.c for
support of the on board sound card - it's working *GREATLY*.

Please revert the changes in question from the pre-patch.
