Alan,

Thanks for the update.

I have a S2881 in my clutches right now and its been working fine with
-CURRENT, although it only has 2GB RAM. It booted and ran 5.3-R fine when
I initially installed it. I have it running in a cvsup + -j16 buildworld
loop with the terminal over ssh.

Here's the relevant pciconf output:

I believe scottl has some fixes to busdma that may be making their way
into RELENG_5 soon. I should probably migrate my machine back down to
RELENG_5 and check for any issues.
