My new Dell laptop's "C/DOCK" has an integrated 3c905.  When I boot
a -current kernel on it, I get the following panic:
...
ep0 at pci1 dev 8 function 0: 3Com 3C905 Ethernet
ep0: MAC address 00:c0:4f:f5:b1:29
ep0: 8KB word-wide FIFO, 3:5 Rx:Tx split,  default mii, autoselect
ifmedia_set: no match for 0x26/0xffffffff
panic: ifmedia_set

trace shows:
_panic(...)
