I saw in the kernel configuration file a broken (???) support for IEEE LLC, which would also mean for IEEE 802.3 frames. If this is working (or get fixed), the only difference to select IPX 802.3 Frames would be the SAP Addresses, which should be both 0xFF. I really don't know how is this section implemented, but this would be easy to do only by adding a SAP entry to another kernel section. That is, one multiplex in the Typespec level, detecting frame types below 1500, and one another at LLC level, detecting SAPs of 0xFF.
