Yes, this was with 2.6.16-rc5 with the suggested patch.

I haven't tried libata.atapi_enabled=1 yet (I'll do it on the first
reboot after this set of tests with Gaussian).


Under both 2.6.12 (as supplied with Ubuntu Breezy) and 2.6.15 (as
supplied with the current Ubuntu Dapper, incorporating 2.6.15.4) we had:

ata1: PATA max UDMA/100 cmd 0x1F0 ctl 0x3F6 bmdma 0x18F0 irq 14
ata1: dev 0 cfg 49:0f00 82:0218 83:4000 84:4000 85:0218 86:0000 87:4000
88:041f
ata1: dev 0 ATAPI, max UDMA/66
ata1: dev 0 configured for UDMA/33
scsi0 : ata_piix
isa bounce pool size: 16 pages
  Vendor: ASUS      Model: DRW-1608P2S       Rev: 1.37
  Type:   CD-ROM                             ANSI SCSI revision: 05

But we didn't use the drive much until now (mostly just for Linux
installation, without CD reading problems) so I have no additional data
on possible issues with previous kernels...
