All: thank-you for the help so far. I have posted this on gentoo-user as
well, and will continue to work with folks individually here or publically
on that list.
The responses so far have helped - Bigfish (Richard), I may respond directly
to your RFI as you may be able to pinpoint the driver(s) I'm missing. I have
added driver support in newly compiled kernels and gotten different errors -
but I think I'm close.
Again all - thanks. I'll pursue on gentoo-user...
