 Hi, Ruslan --- I tried adding 'vinum_load="YES"' into my 
 /boot/loader.conf, as errata.html suggests, but this didn't help with 
 getting vinum to load properly; I still got trap 12 on booting. 
 Unfortunately, I don't have the exact addresses for the {instruction, 
 stack, frame} pointers from that attempt handy at the moment, but I'll 
 send them your way as soon as possible.
