Yes, I know first hand that the HP 520n stock firmware has this feature (and I believe the 420 series also has the same feature) built into its stock firmware.
I installed a 520n in a machine I was building for a good friend of mine, and I was going to change the booktype of DVD+R and DVD+RW using DVDinfoPro, but when I opened the booktype setting window, it already showed the booktype set to DVD-ROM for both +R and +RW media. I immediately ripped an .iso of a DVD-5 and burned it on a +RW disc using DVD Decrypter, and sure enough, the finished product has the booktype set to DVD-ROM. I didn’t have to change a thing.
I later tried to set the booktype for DVD+R media back to +R, just for curiousity’s sake, and DVDinfoPro popped up an error window that the drive does not support bitsetting, so it has to be a feature built into the firmware that HP ships these rebadged NEC2510 drives with.
