the offical lame sources (latest beta) include a debian/ directory, so building
a deb is as easy as debian/rules binary (after you get the build-deps :)

Are you sure they two channels are not sharing an IRQ?

Yep, but the problem there is figuring out how to get each channel on a unique
IRQ. With some BIOSes, it's just not possible.

Be warned of the issues with having two hard drives per IDE channel. I know
that there were reports of massive corruption when using DMA with specific
models of WDC and Maxtor drives on the same channel in DMA mode. You'll also
face some pretty serious performance slowdowns when accessing both drives at
the same time, since most IDE drives cannot do disconnect/reconnect like SCSI
drives can. The best way would be to have one IRQ used for each IDE drive,
which is pretty tough to do on an x86 system. Hopefully your BIOS can allow
this sort of setup, since IRQ sharing still causes a bit of a performance hit.
