Did you clear the configuration of the RAID controller? Is there a way 
you can completely reset it? Can you blank the drives?

Looking at the source, it seems LSI 1030 is supported by the mpt driver 
so it should work. Since you have problems with the boot loader, maybe 
it won't help to build another kernel.

A wild guess could be that there's something on the RAID volume that's 
keeping the boot loader from working. Maybe the partition table is wrong 
in a subtle way? If you can get the RAID array to work *after* you boot 
from a FreeBSD installation CD (i.e. boot the machine without the 
drives, add drives later), try clearing the first megabyte of the array 
(dd if=/dev/zero of=/dev/yourdrive bs=1m count=1).

You need to create a bootable CD, at least. Google around, there are 
several tutorials.
