The second xbox has been modded for almost a 2 years and the 4981 bios disconnects the ethernet.
it tricks software into thinking the ethernet is disconnected, its not foolproof

Are you saying they searched the no. 2 xbox hd, because I have everything booting from F drive including the dash. So how would they know it is modded if the original bios does not recognize F drive?
when a gamertag is flagged they query HD make and model number, if its not a stock HD they ban you

The first gamertag is working fine on another xbox, although it is unmodded.
this is perfectly consistant with a flagged GT, it will work fine with a stock HD

To answer your question, Safrole, the only reason gamertag 1 is on xbox 2 is so when he comes over he can play under his own gamertag. The owner of xbox 2 would never use gamertag 1, he would use his own (gamertag 2)
this wouldnt result in a ban anyway, it would just either not let xbox #2 online, or boot xbox #1 off
as i said, there is also a possibility your GT was flagged due to feedback left on Live, sometimes youll get feedback saying your cheating in H2 if you have a laggy connection (they think your trying to standby glitch) or if your just too good (they say your using hacked profiles)
