freebsd stable - Dec 2004 - pci dma error

I have a diamond mx400 and I get the following error
Maestro: DMA buffer beyond 256MB (busaddr 0x1ed50000 
size 81920)
Couldn't allocate Maestro memory

I am informed on some linux sites that this problem is
related to having more than 250megs of ram.  they
claimed the problem was fixed by manually setting a
dma..  I'm not sure how to do this in freebsd.

ps.  please get back to me off the list as well, I am
not currently subscribed.

This string doesn't appear in the FreeBSD maestro driver, at least in
HEAD.  What is the output of 'ident /boot/kernel/snd_maestro.ko',
'ident /boot/kernel/snd_maestro.ko', and 'uname -a'?

According the commit logs the necessary adjustments to busdma were made to
the maestro3 driver months ago.  What sound driver does the Diamond use?
