Ion drum rocker compatible with PS2?

[DemonDelight]

so im thinking about getting the drum rocker, but im not sure f its compatible with the ps2. i found this compatibility list (supposedly official)

http://blog.wired.com/games/2008/11/official-guitar.html

which tells which instruments work for which systems, and the drum rocker isnt even on the ps2 list. The thing that bugs me most about the list though, is that it says the rockband guitar controller is incompatible with GHWT for ps2, when mine works perfectly fine. Dont know what was wrong with the one they tested.

So im wondering if anyone knows if the drum rocker is compatible with the ps2 version of rock band, rock band 2, and even GHWT
