Hi, Jeremy, Konrad:

Thanks for all your reply. I really appreciate it.

I encountered the following problems:
1. after 'make world' and reboot, the screen would flash some time, so
i removed my graphic card and use the integrated one instead;
2. it seems by default there is a module called 'logitech mouse' which
is not chosen, and guess who's using a logitech mouse?..  it would
stop at boot time and saying some usb problem..

I rebuild and reconfigured the kernel several times, but with no luck..

Then I switched to 64-bit Ubuntu, everything works fine now.

Thanks very much!
