Just so i can get a better idea, what kind of machine is this ?

Well, found some info on the /proc/pci (i had not worked with it before), and whipped up a quick starter ... use at your own risk, your milage may vary ...blah blah blah. Hope it helps.

#!/usr/bin/perl -w

use strict;
my @devices;
$/ = "\n  ";
while (my $lines = <DATA>) {
    my %hash;
    if ($lines =~ m/Bus (\d+), device (\d+), function (\d+):/) {
        $hash{bus} = $1;
        $hash{device} = $2;
        $hash{function} = $3;
    }
    ## parse other lines ...
    push @devices,\%hash;
}

# use @devices
