It is in -current sys/i386/isa/if_ar.c. You can have a look at it. There are some problems with the handling of receive errors that I have fixed but not commited yet. (I am waiting for feedback from one of the testers.) The driver is able to transfer 200+ Kbyte/s with a single channel on a 486DX50. If you are interrested I can send you the patch.
