The ICH4 datasheet also says it has a EHCI debug port. Why is it not supported in LB?

On http://linuxbios.org/EHCI_Debug_Port wiki page there is an info that Intel ICH4/ICH4-M chipset does not supports Debug Port. I have Dell D400 laptop with that chipset and Debug Port is available according to lspci output:
22:47 hrw@maluch:~$ sudo lspci -ns $(lspci|grep EHCI|cut -f1 -d' ');sudo lspci -vs $(lspci|grep EHCI|cut -f1 -d' ')
