Perhaps this is relatet to some BIOS setings, which can be controled with
tpctl or ntpctl (can be found at
http://jhunix.hcf.jhu.edu/~thood/tpctlhome.htm and
http://www.rzuser.uni-heidelberg.de/~mfluch/ntpctl.html)

The later has the menus:

    Int. pointing device (current)     enabled   (ctrable)
    Ext. Pointing device (current)     disabled  (not ctrable)
    Int. Pointing device (CMOS)        enabled   (ctrable)
    Ext. pointing device (CMOS)        disabled  (not ctrable)   

The posible values are [e]nable, [d]isable, [a]uto, and perhaps some are
set to auto and therefor is the internal pointing device not recogniced
when the mous is pluged in. Try to experiment with these values and see
what happens (I by myself has no experience with that ... just a thought)
