Dhruba, I put a fair amount of effort into this problem (also running Gentoo, with many different kernels), and ultimately concluded that the problem was with the chipset - inserting the uhci or usb-uhci modules consistently locked up the PS/2 keyboard. I also tried USB-to-PS/2 adapters for the mice, but those mice don't speak PS/2. The only solution was to fork out an extra $25 for a USB keyboard, which works fine on all the machines I've tried.
With regard to your last question, I don't think all the USB ports are the same. When I plugged the keyboard and mouse into the two jacks next to the ethernet port they would occasionally fail to be recognized, but they work consistently if I plug them into two of the four ports below the ethernet jack. I haven't tried the front ports yet. Hope this helps! -A.J.
