G41: UltraBay Enhanced Hard Disk Adapter?

[A.C.]

One of the great things I really like about my A22m is that I can carry 320GB of disk space (160GB in the main disk bay, 160GB using the UltraBay 2000 Hard Disk Adapter).

Alas! The G41 would be equally awesome if I could only stick a 160GB hard drive into the UltraBay 'Enhanced' space occupied by the DVD/CD-RW drive.

Does anybody know if hard drive adapters for other series (like the R series) work (or can be made to work) in the G41?

Thanks!
