The kernel 2.6.27 detects the following ioports in the motherboard MSI
Fuzzy GME965:

0800-087f : 0000:00:1f.0                                                                                   
  0800-087f : pnp 00:08                                                                                    
    0800-0803 : ACPI PM1a_EVT_BLK                                                                          
    0804-0805 : ACPI PM1a_CNT_BLK                                                                          
    0808-080b : ACPI PM_TMR                                                                                
    0810-0815 : ACPI CPU throttle                                                                          
    0820-0820 : ACPI PM2_CNT_BLK                                                                           
    0828-082f : ACPI GPE0_BLK
    0860-087f : iTCO_wdt

It seems this is done with a PCI quirk.

According to the motherboard manual the I/O Map for the ACPI I/O Space
is: 0400-045F

Here is the link to the motherboard info page:


The same situation is in the kernel 2.6.24 in Hardy.
