I had two desktops and a laptop, none of which would run 9.04 without freezing. I used F6 at the first screen following language selection on the live cd boot to x out apic and lapic for the boot. When That fixed the problem I proceeded with the install from the live cd. You can try it with the live cd before commiting to the install. If installed from the live cd the kernel options noapic,nolapic will be automatically added to the boot options.
