    The driver rewrite is almost complete (after being preempted several 
times), I'm awaiting it to also be tested on HPT302. The changes are HUGE, the 
patch is about 70 KB in size...
    Meanwhile, I've noticed (just now :-) a bug in HPT372N clock turnaround 
code (it accesses extra DMA ports relative to dma_base, not dma_master which 
would make it do BAD things if called on a secondary channel) -- guess I 
should post them in a separate patch?

WBR, Sergei
