Description:
In the detectpci() function, $Num is supposed to be set to a unique identifier so that lspci -m | grep $Num will only return one line. However if you have:
$Num == "00:00.0"
(Like I did running Arch i686 as a client under VMWare Workstation V6.02 x64)
Then that will also match:
"1000:0030" because it contains 00:00.0 where . is anything.
(Having multiple lines returned causes odd problems with an invalid file being generating and odd error messages)

We actually want $Num to be "00:00\.0" so that it only matches the proper case.
(Additionally it might make sense to require it be at the start of a line)

I fixed this by changing:
Num=`echo $LINE`
to
Num=`echo $LINE | sed 's/\./\\\./g'`

on line number 82

Steps to reproduce:

Have hardware that causes lspci to output multiple lines when running grep with a unescaped period
