[tulip] Problem with tulip, 2.4.0test kernel

Hi,
Config is two PIII boxes, RH6.2, kernel 2.4.0-test9 (tulip driver lifted
from kernel 2.4.0 - version 0.9.13 (January 2, 2001) but was previously
using the proper 2.4.0-test9 driver - version 0.9.10 (September 6, 2000))
and Znyx ZX346Q 4port cards, with each port connected to the corresponding
port in the other PC via a crossover cable. Tulip driver is built as a
module. Other nic in the PC is a builtin 3c905C.
Using the tulip driver that came with the 2.4.0-test9 kernel, or the latest
kernel, produces the same effect: a fresh boot of the PC will load the tulip
driver and ifconfig the interfaces, but the interfaces are not actually up -
I can ping the interface itself, but I cannot ping the other PC. If I load
the de4x5 driver instead, I _can_ ping the other PC. (Another odd thing is,
if I load the de4x5 module, ifconfig the interfaces, then deconfig them,
unload de4x5.o, load tulip.o and bring the interfaces up, it seems to work
properly.) If I connect the ports to some real hardware such as a switch,
the ports will work okay.
dmesg shows:

Now, if I run tulip-diag -m (or -mm), it tells me there are no MII
transceivers. However, if I run mii-diag, it shows:

You have link beat, and everything is working OK.
Your link partner does not do autonegotiation, and this transceiver type
does not report the sensed link speed.
So, not only does the link operate sporadically when connected to another PC
instead of a switch, the diagnostic utils appear to report conflicting
information - at least, the way I interpret the reports indicates so.
Anyone have thoughts as to what is going on here and how I can get this
working?
Also, how can I force a specific speed? I know I can pass 'full_duplex=1'
to the module to enable full duplex, but what do I pass to force 100TX
instead of 10BT?
Cheers!
