bug report: AMD64, 5.3, sym driver

I believe that I've found a bug with the sym driver in AMD64.  I don't 
have this problem with 5.3 under i386.  I wasn't able to submit this 
report via web because the anti-spam code wasn't being recognized.

The problem occurs during boot up / driver detect.  I get the following 
messages in bootup which I've manually copied:

sym0: <810a> port 0x9000-0x90ff mem 0xea094000-0xea0940ff irq 12 at 
device 7.0 on pci1

I was using the mini-inst boot CD from the iso images.  I had to disable 
ACPI at bootup to not hang later in the boot sequence (after the 
detection of the single IDE device installed - a cdrom).  This 
particular machine has a motherboard with an nforce3 chipset.  As I 
mentioned, I don't have this problem with the i386 branch, but I do 
still have to disable ACPI.  I tried an older version of AMD64.. I 
believe 5.2.1, and got the same result.  One other thing to notice is 
that it also has a problem with my Symbios 810 card.  Of course, as a 
result of this, none of my scsi hard drives are recognized and I can't 
install.
