add audigy support to emu10k1 driver

Hello,

This patch updates the emu10k1 driver to its 0.19a version so that
audigy cards should work under 2.5.x without needing ALSA. This is a resend of this patch with the attachment as a bz2 file instead of being plain text, this is because my previous two mails have never managed to hit the list, sorry if they ever do and this is yet another post of the same patch. Thanks.

Jordan
