Sure.  That's what ftdd (part of VRN) does.  VRN is a replacement
kernel module for Sierra's VI (virtual irq) driver, and SubLogic's
FTDD driver.  It's a standard part of NitrOS-9.  You'll want the
actual package, it's on RTSI, mainly because it includes docs and
sample source.

Do note, however, that FTDD doesn't do ALL the work for you.
