network trouble on 68360 (ACE360/HSB)

Yes I'm still having problems.
According to the users manual for the ACE360/HSB board, this is the mapping
of the IO:
PA0 Ethernet RxD
PA1 Ethernet TxD
PA8 Ethernet TCLK
PA9 Ethernet RCLK
PB12 Ethernet *RTS
PB16 Ethernet link test
PC4 Ethernet CLSN
PC5 Ethernet RENA
With a multimeter I've verified this wiring is correct.
Looking at "network.c" under the gen68360 bsp in the HSB defined section it
appears that the IO is being set up properly. (that doesn't mean that
something somewhere else isn't messing with it)
This board is using the LTX901 PHY. I even tried tying the link test pin to
VCC (to disable full duplex as suggested in the datasheet)
The boards that I have were removed from some prototype ADSL modems from a
company called "Aware." The board has many chips de-populated so it's
possible that there might be a "slight" difference in this board vs: a
"normal" ACE360/HSB. Since Atlas was bought out, I have no way of contacting
them to ask.
Any help or suggestions you have would be greatly appreciated.
Thanks in advance,
