OS X 10.5.2 usb controller plus update

[culle]

Hi everyone.
After several trials and failures of installing Mac OS X i've finally got it working with Zephiroth's 10.5.2 AMD rev2. I have two problems. First one, bigger, is that USB isn't working. The system works perfectly if I disable controller in BIOS. But if I enable it it stuck while booting (the gray background and Apple logo). What can i do?
My specs are down here.
Second problem is updating to 10.5.8 but i think i found solution here so pls help me fixing USB.
Tnx
