No mouse in Herd 2 Desktop CD on Virtual PC

I have the Herd 2 Desktop CD 20070111.1 and when I use it to boot into the live environment on Virtual PC 2004 there is no mouse capture. This means I can't click on anything using the mouse. The best I get is a dashed line square when I click and drag. Though this might no be happening in ubuntu because nothing underneath is selected.

Checking dmesg only turns up the line
[ 42.056365] mice: PS/2 mouse device common for all mice

There's nothing displayed with lsusb, but this appears to be normal since it is the same on dapper and the mouse works there.

Checking /proc/bus/input/devices shows no "mouse" anywhere, on Dapper there is an entry for the mouse
I: Bus=0011 Vendor=0002 Product=000a Version=0000
N: Name="TPPS/2 IBM TrackPoint"
...
H: Handlers=mouse0 event2 ts0
...

I realise that this isn't going to be a high priority, but it prevents me from installing using this CD as I can't get past the locale select in ubiquity with just a keyboard. Unless there's a way I can't see.
