Hi there,
there is a bug in the at91rm9200_ether.c. The pins are configured wrong due to the new introduced
"#if defined(CONFIG_AT91C_USE_RMII) && !defined(CONFIG_CMC_PU2)".
The pin configuration is now done jsut like in linux-2.4 and linux-2.6
* Patch by Steven Scholz, 13 Dec 2004: Fix bug in at91rm920 ethernet driver
