Echo CardBus driver

["Yon Mercury" <swirlee@stickist.com>]

Giuliano,

OK I solved the compilation problem by going straight to my laptop (I was 
testing compilation on my desktop without PCMCIA kernel support)...

I went out and picked up the Indigo IO card, installed it in Windows and 
tested it-- all OK. I compiled and installed the echo patched alsa and 
rebooted. 

I didn't edit modules.conf to add a snd-indigoio alias for ALSA, but it 
didn't seem to matter. The cardbus support loaded fine and the blue light on 
the Indigo came on (woo!). Though the driver seemed to detect an IndigoIO, 
there was an error in the DSP init:

This is on kernel 2.4.25 from a Demudi base installation.

Not bad so far!
