Hi,

NetBSD maps to 0xcb166000, and if I poke about at around that address I
can read interesting things like the string "ATMEL" so that seems to be
where the CIS is.

FreeBSD reports that it is mapping to 0xc91cc000.  If I poke around at
this address all I get is zeros and the odd random integer.

Regards,

Stuart
