use of moused on 5.3-BETA1 causes hard freeze

Hi,
	Since cvsuping and recompiling I can no longer use moused as it
lock up the computer (or at lease freezes mouse and keyboard, i havent
had a chance to see it i can ssh in post moused.) computer is a toshiba
portege A100 and uses a synaptics touchpad, last cvsup was yesterday

psm0: <PS/2 Mouse> flags 0x1000 irq 12 on atkbdc0
psm0: [GIANT-LOCKED]
psm0: model Synaptics Touchpad, device ID 0

or withough the 0x1000 flag (only tried that as i needed it for 4.x)

I'm aware that the synaptics support is being looked at but it doesnt
mention breakage to this extent

I'd be happy to provide any extra info if it'll help, but i'm not much of
a programer (only using the 5.x series in the hope of getting if_ndis
working)
