you're right it sounds feasible, it would seem to me that you would have to wire it in some way similar to a 29 wire mod... I would assume there would be some complucations though.
I would suggest using a newer bios release from now on... if you're partial to the xecuter releases get X2 4983 it's stable and should give you trouble on any version (1.0 - 1.5).
You're only real options are to either throw a few bucks into a modchip (i'd suggest geting something cheap like the aladdin advance, or duoX2) or investing in a cheapmod. If you want to get your tsop back you bould get a 29-wire mod, or try to get flashing from a chamelon working (something i have yet been able to master). A cheapmod or cheam modchip would probably be the easiest way to go,
divineo.cn is probably the least expensive place to get them from if you're willing to wait a couple of days for shipping.
GoodLuck
::EDIT:: The
Aladdin XTs are looking pretty tempting too... only $10 + SH
