Problem with mouse on T60

Hi all,
I'm installed current version of FreeBSD (FreeBSD 8.0-BETA2) on laptop ibm T60 and I have problem with internal mouse (touchpad and pointing mouse). In time booting 'kernel: psm0: unable to allocate IRQ'. I try to disable (into BIOS) the touchpad or pointing device, but problem still the same. A try to applied patch (see below) but problem again still the same.
Code:
/usr/src/sys/dev/atkbdc/psm.c
/* device I/O routines */
static int
enable_aux_dev(KBDC kbdc)
{
    int res = PSM_RESEND;
        
    res = send_aux_command(kbdc, PSMC_ENABLE_DEV);
    VLOG(2, (LOG_DEBUG, "psm: ENABLE_DEV return code:%04x\n", res));
        
    return (res == PSM_ACK || res == PSM_RESEND);
}

IRQ 12 is not busy:
Code:
# vmstat -i
interrupt                          total       rate
irq1: atkbd0                       10642          2
irq9: acpi0                        16078          3

irq259: ahci0                     123855         23
cpu1: timer                      2098649        399
Total                            4950218        942


On other system internal mouses work fine.
Thanks
