I have the same issue with the Ubuntu/Kubuntu 64bit Alternative CD and
64bit DVD. After the black screen with the cursor, if you are patient
enough, after 3 minutes you will have an error saying it can find the
CDROM device. As for USB mouse and keyboard, If you wait 2 minutes it
will start to work. When I finally managed to access the console, there
was no device for the CDROM. With ot without NOLAPIC as boot parameter.

I was running OpenSuse 11.2 64bit and the only way to install with USB
mouse/keyboard, was to set NOLAPIC in the boot parameter to get the
mouse/keyboard to function. After the siystem was installed it was no
required. When I updated the kernel to 2.6.32 USB devices started to
acting up and this wait time of 2-3 minutes appeared. Tons of USB error
messages started to appear.

Since when I launch Kubuntu or any other distros I have this wait time
(NOLAPIC or not). I am starting to thing the 2.6.32 kernel might have
brick my DVD/USB/Motherborad partialy.

I was able to install Windows XP (needed to being able to acces the
net). Something who look somewhat related is within WinXP I need to go
in the Device manager and redetect hardware to get the DVD drive to
appear. Might be realted to the Netbook version of XP tho.

For now I am stuck in XP/IE. Next step is to flash the bios.

Computer specs:

ADM Athlon 64 X2 3600+
2GB of DDR2 667 RAM (128MB shared with video card)

etc)

Nohing is overclocked.

Os Tested on it: 
- Windows 7 RC2 (Stable for months)
- Windows XP Home HP mini 110 version (Stable)
- OpenSuse 11.2 (stable for months but USB/DVD Acting up since new kernel 
and/or some security updates)

I hope it can help.
