This has been fixed in the actual release of 2.6.16-ide1 which i've just 
booted into.  DMA seems active (as you'd expect since non-dma isn't 
supported) and no irq trap delays.   Everything is working good again,   
Now if there was a way to get the CF disk (doesn't do dma) working in 
pata, I'd be set.

ps.  Thanks for the help, I wasn't aware of the ide1 patch to 2.6.16 
before.
