| Sound is broken.

| shouldn't be.  WLAN is also broken by DMA-related issue so maybe it is
| the same thing.

Sound and WLAN are fixed... both caused by a return code in
s3c2410_dma_request() changing meaning.

The WLAN helper thread still throws a warning about being blocked for
|120s by default on Linux 2.6.25-rc9 but I think it is by design.  I can
associate to my AP OK on the WLAN and the rootfs plays its hello sound
and touchscreen taps work OK.

Suspend looks like it works fine from X as well, but I forgot that I was
booting from microSD so it blew chunks on the filesystem.   It came back
as it should have other than that, so I think it is OK.

The only known things we didn't fix yet is a compatibility sysfs symlink
for GTA01 and the 120s WLAN thread noise (the warning explains you can
turn it off down /sys).
