Hi,

after looking at my ethernet card for quite some time and wondering about
the discrepancy between

espresso /netbsd: ae0 at nubus0 slot c: Ethernet A-Series, 32KB memory
espresso /netbsd: ae0: Ethernet address 00:40:10:02:0f:26

and what the fine print on the RAM chips says (2x 32k) I finally UTSL'd.
Patching if_ae.c like...

...gave me...

espresso /netbsd: ae0 at nubus0 slot c: Ethernet A-Series, 64KB memory
espresso /netbsd: ae0: Ethernet address 00:40:10:02:0f:26

-- Does anybody see any problems with the change?
