UMTS connection with nozomi driver unstable -> workaround might be implemented

Description

UMTS connection through an OPTION card (e.g. T-Mobile web'n'walk card compact) in HSDPA mode often crashes the router under havy (especially up-)load (e.g. video conferencing, file upload). This leads to a reboot of the router (WRT54G3G) making any heavy use impossible. The ppp workaround found at http://www.pharscape.org/component/option,com_forum/Itemid,68/page,viewtopic/t,51/sid,c91a255ab908630303a66e546a54c0bc/ solves this problem. This workaround could be implemented into FreeWRT until a solution from the driver side can be found.
