Pull up revision 1.17 (requested by hubertf in ticket #1322):

Disable ISA DMA emulation for SoundBlaster module explicitly.
This fixes the floppy access problem on some hardware.
Problem reported by Miroslav Kure via Jason Wright <jason [at]
thought [dot] net> of OpenBSD. Thanks.

Fix from ALSA driver; although this setting is undocumented but
according to Jaroslav Kysela <perex [at] suse [dot] cz> of ALSA,
there's no error reported so far.
