Unfortunately I think you'll find there are sufficiently large numbers of broken SOHO routers out there that if you try this you'll cause a lot of problems. The problems range from no connectivity to in a few extreme cases routers actually crashing or behaving in very unpredictable ways. Here's one summary that got presented to the IETF about 18 months ago:
http://www.ietf.org/proceedings/07mar/slides/tsvarea-3/sld6.htm
When a clueless end-user gets a Linux-enabled netbook that crashes their router while their existing Vista or XP systems appear to work just fine then the Linux network stack will get the blame for being buggy, not the router :-(
