It works for me, xl0 card is recognized.

But during heavy ftp network traffic the LAPTOP panics.

As a test I wanted to download the 5.1 SNAP ISO image from
my 5.1-current FreeBSD server (PIII 1GHz, 512 MB DRAM, fxp0).

Under Windows XP this ~300 MB file gets transferred with about
9-9.3 MByte / sec.

Using FreeBSD 5.1 on the laptop it starts with about 8 MByte/sec
grows up to 8.3 KByte/sec 

but then after 115 MB the transfer stalls.
After about one minute the kernel panics.

panic: sbflush: cc 4294967244 || mb0 || mbcnt 0

syncing disks, buffers remaining ... 1814 1814 1814 1814 
     1814 [ repeated ~20 times]
giving up on 18 buffers.

The kernel was basically a stripped down GENERIC kernel without
-currents debugging options.
