Mmm.. through ATA interface? I guess this is a tricky thing.

One i can ack is USB-CompactFlash adapters work very well on NetBSD. I'm 
flashing CF cards on "8 in 1" Apacer MG820 adapter without any problems. Of 
course no problems with card hot-swap too.

By the way:

$ dmesg

umass0: using SCSI over Bulk-Only

$ ls -l /dev/sd*d
brw-r-----  1 root  operator  4,  3 Jan 28 13:37 /dev/sd0d

-> so if i connect two adapters at the same time [my case] default system 
installation goes out of /dev/sd* entries.
