Pre-requisite:

I have ZFS raidz1 pool on 6 disks distributed between 4 SATA channels on 
onboard MCP and 2 internal SATA channels of SATA300 TX4 on my test machine; 
before I had constant errors on ad12 and ad16 (machine is not under load, so 
no harm to actual data).

Problem:

After you patch ad12 and ad16 have been recognized, but it seems driver 
changes some offsets, as there are no ad{12,16}a partitions anymore, and 
fdisk -s ad12 gives me

fdisk: invalid partition table found

while before it produced something like

/dev/ad4: 486344 cyl 16 hd 63 sec
Part        Start        Size Type Flags
   4:           0       50000 0xa5 0x80
