-using cfg-loader entry point now, its a bit lower ;)

-clearing screen properly now, no green screens or things like this
-added a few more low mem settings, fixed a missing flush in set
video mode (thanks dimok)
-partially clearing mem1 too now, using the code of cfg-loader for that
(thanks)
-using asm volatile instead of __asm__ to really call what we want
(thanks dimok for explaination)
-deiniting usb device properly
-shutting down system properly now on game boot, games should boot
more often now, its still not fully fixed
