It was the first time I ever tried it. Now as you asked I also tried
2.6.12-rc5. Surprise, surprise - it worked... But very strange. First, I
did
# time cp -a source /cdrom/ ; time sync
It took a few minutes to copy 190MB, but it finished successfully. Now to
the strange things: even after it finished the LED on the writer continued
flashing red... Only after I performed a read access to /cdrom/ it
stopped. Actually, just wrote a small file to it, did a sync, sync
returned, LED is flashing red. Now I cannot stop it by reading. Only
unmounting it helped.

Yeah, seems to be. But, likely, unusable for me - I don't have Windows at
home. Don't know how relevant that BIOS upgrade would be. Here's comment
from the BenQ site:

Firmware Update
Changes:
1. Fix misjudgement for 8cm CD-R disc.
2. Solution for CD Extra reading issue.
3. Enable quality test function on CD-DVD Speed v3.x.

Besides, it works under 2.6.12-rc5...
> Does it work if you use ide-scsi instead of ide-cd?
No. I get
# mount ./pktcdvd0 /cdrom -t udf -o rw,noatime
pktcdvd: inserted media is CD-RW
pktcdvd: Fixed packets, 32 blocks, Mode-2 disc
pktcdvd: Max. media speed: 10
pktcdvd: write speed 10x
pktcdvd: 590528kB available on disc
UDF-fs: No partition found (1)
mount: wrong fs type, bad option, bad superblock on ./pktcdvd0,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Well, to compare packet / "normal" I just tried the same CD-RW with
cdrecord as /dev/hdc at the same speed 10 (max for this CD) - it worked.
