Maybe its time for a ipod upgrade?
Not likely to work. Primary reason is due to RAM size, after that is CPU arch (though the iPod touch 2nd gen supported most of the 4.x trunk), finally, is missing features (mic, BT, etc).
Overridding most of that.... the old SoC is just too slow.
The iPod Touch 1G has the same CPU, RAM, and GPU as the iPhone 3G. And that got iOS 4.2.1.
