Here I've a new Dell Inspiron 6000 with Debian Sid and I see similar
messages in dmesg (2.6.14) when I start k3b.
I've to say that libata.atapi_enabled=1 trick doesn't work for me (neither
modprobe.conf option) and I need to change that value directly in
libata-core.c.
Few days ago, I've tried a newer 2.6.15-rc4 with Jeff libata1 patch, and I
see tons of these in the log:

and kde hangs in one of the steps of ksplash before showing desktop ( I
think, trying to discover media, such as cdrom, usb pen drive and so on).

PS: To Jeff Garzik: I try to sent you two mails about this bug but I
think they were not correctly delivered... sigh!
