I'm a little late replying, but I thought I would reply if only for archival 
searches on this subject.

I have an Acer C300 TabletPC and the BIOS does not support booting from USB.

This doesn't matter, however, since you can install a boot loader onto the 
LAPTOP'S hard drive that will boot the USB partitions for you.

I don't recall if the FreeBSD boot loader does this, but GRUB 
(/usr/ports/sysutils/grub) definitely does.

Here is my grub /boot/grub/menu.lst:

--------------------------------------------------

title WindowsXP
rootnoverify (hd0,0)
chainloader +1
makeactive
savedefault

title FreeBSD RELENG-5
root (hd0,1,a)
kernel /boot/loader
savedefault

title FreeBSD RELENG-6
root (hd0,2,a)
kernel /boot/loader
savedefault

title FreeBSD Portable Disk
root (hd1,1,a)
kernel /boot/loader
savedefault

title OpenBSD Portable Disk
root (hd1,2)
chainloader +1
makeactive
savedefault

--------------------------------------------------

As you can see, on the laptop's hard drive (hd0), I have WindowsXP and two 
FreeBSD installations.  On the USB drive (hd1), I have a non-bootable DOS 
partition (no entry but would be entered hd1,0), a FreeBSD partition, and an 
OpenBSD partition.  

I hope this helps some.
