 I suspect ohci and bnx not working also has something to do with the amount
 of RAM. bnx gets memory allocation failure in bus_dma(9) and it could
 be what's preventing ohci from starting too.
 
 For the disk controller, it's an Adaptec ASR2120S. The ASR2200S is supported
 by aac, maybe adding the 2120 to the table would make it work too (once the
 bus_dma issues are fixed) ?
