dual layer writers

[holiday]

I saw a pack of Verbatim that included one DVD+R DL at Best Buy. It was thirty dollars, but included 8 redular DVD+Rs and 1 DVD+RW along with the dual layer disk.

Has anyone figured out if any of the current single layer writers, like the NEC ND-2500A or the Pioneer A07/107 will be able to be flashed to dual layer capacity? Or if the PS2 will be able to even read burned DVD+R DLs, given how poorly some PS2s do with DL games?
