Hi folks...

I've just committed a whole slew of code, the point of which was to
implement a bus_dma back-end for the Shark.  It's been running for a
while on my Rev 5 just fine.  Step one to getting audio working again :-)

NOTE THAT UVM IS NOW MANDATORY ON THE SHARK!!  Otherwise, the ISA DMA
ranges won't be protected from random free list page-grabbers, and
e.g. the Ethernet driver won't be able to allocate DMA buffers.

Note that I also did some playing around with using the ESS chip's
sound blaster compat mode, but I couldn't get sound to come out.  I
suspect this is because the OpenFirmware properties for the audio,
ethernet, etc. are totally wrong on my Sharks, and I'll have to
fix them w/ an nvramrc hack before the `ofisa' drivers can be sanely
used.  Sigh.

If you have any problems, please send a bug report w/ send-pr(1), and
I'll deal with it ASAP.

Have fun!
