I'm getting a fatal trap 12 every time I try to kldload atapicam on 
BETA2 as well, but I'm not getting a vmcore or anything ...

acd0: DVDR <MATSHITA DVD+/-RW UJ-875S/D200> at ata0-master UDMA33

So, basically, I can confirm kldload atapicam crashes my system but I 
can't provide any cores or anything .. Im probably missing something 
and that's why Im getting nothing under /var/crash .. should anyone 
want to enlighten me with a link to read how to get the vmcore, I'll 
read it and try to get it so I can provide more info.

Best regards
Gonzalo
