As in Object: this has been reported by many user I know, with different chipsets and different IDE cd-burners. Bug wasn't in 2.6.8 rc4.
cdrecord output with kernel 2.6.7 and kernel 2.6.8.1 as root:

cdrecord output with kernel 2.6.8.1 as normal user:

Please note that no supported modes are found. There are many other errors reported with cdrecord -atip or when trying a c2 errors scan with readcd:
cdrecord: Operation not permitted. prevent/allow medium removal: scsi sendcmd: no error CDB: 1E 00 00 00 01 00 status: 0x0 (GOOD STATUS) cmd finished after 0.000s timeout 40s
The same happens with CyberDrv CW088D CD-R/RW and PLEXTOR CD-R W4012A, between the others.
