I see, so it's not vpac270 bug.

You don't really need to configure these if you then set it to AF2.

Zylonite 300 uses value 0x3c for the SMC91111 in the corresponding part of MSCx 
register in original Marvell sources, Zylonite320 uses 0x123c ... maybe you 
should review the MSCx configuration here. For pxa27x, I guess it might be 
something like 0x123c too.

From the log below, it really seems the ethernet chip is choking.
