Bug#520285: installation-reports: The squeeze netinst dosn't configure DHCP

[Julian Hughes <julianhughes@gmail.com>]

I can reproduce this bug exactly using squeeze i386 netinstaller of 31
May.

hardware Asus M5N laptop, wired network interface Realtek
8139/8139c/8139c+ (rev 10). Laptop is essentially Intel ICH4.

DHCP works and the expected IP address is allocated by the router but
then netcfg fails error code 139.  I checked using static IP and netcfg
fails as well but also libresolve segfaults. 

The network interface and the router are both proven good by the fact
that the Lenny installer works, as do others such as BSDs. And in vtty2
dhclient works fine.
