Yes. I have ATA disks running, and I'm close to having the ATAPI
part done also. So far things are looking very good, performance
is up one notch on all the ATA HW I have in my lab.
I have no projected date for this yet, but progress is speeding up..

It "should" work, but the promise support in the old system is, well,
hacky at best. I'm not sure if Promise supports more than one card
at a time, but from looking at the chip specs, it should work just
fine, and if the hardware works, at least the new driver will support
it.
