Great, thank you! However I had to increase MSS_DEFAULT_BUFSZ to 65KB and
decrease hw.targetirqrate to 16 to provide better skip protection during kernel
activity (mostly syscons output), but after those tweaks it works perfectly!

P.S. Perhaps it would be good idea to decrease default irqrate from 32 to 16,
because I had a reports from a friends who have similar problems with skipping
during syscons activity on various audio chipsets.
