Dang.
Could you please try the following debugging printks and send me the results? (Please add the lines beginning with '+' by hand, removing the plus signs.)
What kind of machine is this?
Any others with problems with the PS/2 mouse on pre-8?

kb_wait(); outb(KBD_CCMD_WRITE_AUX_OBUF, KBD_CNTL_REG);
kb_wait(); outb(0x5a, KBD_DATA_REG); /* 0x5a is a random dummy value. */
status = inb(KBD_STATUS_REG); while (!(status & KBD_STAT_OBF) && loops--) { mdelay(1); status = inb(KBD_STATUS_REG); }
if (status & KBD_STAT_OBF) { + printk("kbd status reg: 0x%02x\n", status); val = inb(KBD_DATA_REG); + printk("got 0x%02x from kbd data reg.\n", val); if (val == 0x5a && (status & KBD_STAT_MOUSE_OBF)) { printk(KERN_INFO "Detected PS/2 Mouse Port.\n"); retval = 1; } }
