Did a preliminary install of 9.0 last night (mostly to get a feel of things). Noticed that my USB mouse was not being detected on boot - its plugged into a hub, not directly into the back of my PC. When I had a look at dmesg, I spotted a line that compained that usbdevfs had invalid remount parameters (posting from work so I can't give you the precise message at the moment, I'll try to do that tonight).
Solution was simple - I reset /etc/sysconfig/usb to load the USB modules "early" in the boot process. Mouse worked after that. However this still needs to be investigated. My machine is a dual P-III 1GHz, with the "noapic" argument set in the kerenl parameters (buggy BIOS). Other than that 9.0 is looking great!
