[bug] 2.6.8: CDROM_SEND_PACKET ioctls failing as non-root on ide scsi drives

kernel 2.6.8. ioctl ("/dev/hdc", CDROM_SEND_PACKET, cmd)
commands that are failing as non-root, even when permission is granted
rwxrwxrwx to /dev/hdc, are, according to some debug info added to k3b:
GET CONFIGURATION (46)
error code: 0
sense key: NO SENSE (2)
asc: 0
ascq: 0
and:
MODE SELECT (55)
error code: 0
sense key: NO SENSE (2)
asc: 0
ascq: 0
the result is that k3b cannot determine that the drive exists, therefore
it cannot use it even though cdrecord might actually work.
as root, the following errors occur:
MODE SELECT (46)
errorcode: 70
sense key: ILLEGAL REQUEST (5)
asc: 26
ascq: 0
READ DVD STRUCTURE (ad)
errorcode: 70
sense key: NOT READY (2)
asc: 3a
ascq: 0
presumably it can be concluded that the GET CONFIGURATION ioctl command
is the one at fault.
... what gives?

around you, funnily and coincidentally enough, life gets a lot better.
