amd64 and tx2000 compatibility

[mcomb at softcoin.com]

Hi, I just setup a shiny new AMD64 box and I'm trying to get FreeBSD 
5.3 release installed on it.  As it boots from the install CD it 
displays LOADER briefly and then immediately reboots.  If I remove my 
RAID card (Promise tx2000) it seems to boot fine.  I searched the 
archives, but couldn't find anything relating to this specific card.  
Should it be supported?  Anybody have a workaround besides going to the 
32bit distro?

Thanks,
-Mike
