CF cards / ATAng / interrupt code still broken

Hello,

as reproducable seen on my IBM Thinkpad, current as of some days
ago has problems to boot with my 128MB noname CF card inserted.
The panic output is very similar the problem Alex Dupre reported
in mid of september, but Sorens patch which should be tried to
get this stuff fixed but the patch does not help.

These messages get logged while booting verbose:
(... beginning removed because it's probably not interesting)

If I insert the card after the system is up and running the
panic does not appear, probably because ATAng does not get
the information about a newly inserted drive?
At least atacontrol list does not display any drives:
desire:~>sudo atacontrol list
ATA channel 0:
    Master:  ad0 <TOSHIBA MK6021GAS/GA023A> ATA/ATAPI rev 5
    Slave:       no device present
ATA channel 1:
    Master:      no device present
    Slave:       no device present
ATA channel 2:
    Master:      no device present
    Slave:       no device present

If there are further patches available I would like to test
them in order to use my CF card again ;)
