The Fireport 40 uses a slightly different chip ID/revision ('875j) than
FreeBSD 2.2.2 knew about. FreeBSD 2.2.5 should work perfectly. There was
a patch posted in the list archives that you could use as a quick fix.
Looking at /usr/src/sys/pci/ncr.c on my recent 2.2.5 I see:
#define NCR_875_ID (0x000f1000ul)
#define NCR_875_ID2 (0x008f1000ul)
If you simply change your NCR_875_ID to the NCR_875_ID2 value shown,
then rebuild your kernel, you'll be in business. I think. Your Mileage
May Vary. Perform At Your Own Risk. Etc.
