[LinuxBIOS] EHCI Debug Port on ICH4/ICH4-M chipset

[Marcin Juszkiewicz]

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' ')
