I got complete -current sources tree from releng dated as 20040711 and tested 
on my target machine. Looks like -current works much better in respect to 
Compact Flash cards :) 300kb/s in synchronous and >1Mb/s in asynchronous mode 
is good.

Well, there's IMHO last question: why CF card is configured to use PIO mode 
0 ? I know my card supports PIO mode 2 and it actually reports its 
capabilities in ATA identify response. At least i can trace this responce in 
ata_get_params() call. But somewhere futher this information is discarded and 
wd0 becomes PIO mode 0..

I want to see this changes in NetBSD 2.0 ! :) This really makes the life 
easier for people like me who had to use brain damaged Compact Flash cards..
