[ale] ThinkPad sound working

[Bob Toxen]

Yup, DMA working:

hdparm /dev/hdc

/dev/hdc:
HDIO_GET_MULTCOUNT failed: Invalid argument
IO_support   =  0 (default 16-bit)
unmaskirq    =  0 (off)
using_dma    =  1 (on)
keepsettings =  0 (off)
readonly     =  1 (on)
readahead    =  8 (on)
HDIO_GETGEO failed: Invalid argument

I guess X needs customization.  Blech.
