Only 64 MB memory recognized - HP xw4550

Hi,

I'm attaching a dmesg from 7.0-BETA4, i386, on a HP workstation with an 
Opteron CPU and 2 GB memory. The main problem is that only 64 MB memory 
is recognized by FreeBSD (the BIOS and the FreeBSD loader account all of 
2 GB). This is a "FYI-only" post as I don't have the hardware any more. 
Maybe someone gets an idea about the problem.
