Even if the software worked, pairing the joypad might not be impossible (at the moment) - there's currently no low-level support for the bluetooth stack. I tried unsuccessfully to pair a PS3 and a Wii controller due to the same issue. HP could of course fix that in an update, if they wanted. Wii and PS3 remotes work well on TP running Android by all accounts.
OnLive is working for Android, so may well work with dual booting your TP.
