Ok, I tried to boot from
	1) 5.2.1 i386 ISO w/ twa.ko loaded (from 3ware.com)
	2) 5.2.1 i386 ISO w/o twa.ko
	2) 5.2-CURRENT amd64 ISO from snapshots.se.freebsd.org
	3) My own 5.2-CURRENT iso

They all panicked on boot with (bear with me, I have to hand type this):

ata3: at 0xfeafec00 on atapci0

shutting down ACPI

I've also tried disabling ACPI and it does the same thing. Incidentally, 
I'm pxebooting this server and installing from the ISO images via NFS. 
Could this be why it's panicking? If so, I'll have to go and hunt down a 
spare CD-ROM drive.

Also, when the current installation has booted, geom disk list prints out:

Should the modes be r0w0e0?
