At what line speed? You probably had some bad HW. I was running a 486 DX2/66MHz box with userland pppoe + nat without any problems on a 1,5Mbit DSL line. It got replaced because it was too loud not because it lacked power. For 6Mbit line you would have to use kernel pppoe, userland pppoe would kill the box. RAM is more likely to be a problem. 16MB I had in that 486 was enough for OBSD 3.0 but now is probably a bit problematic (read up on turning on swap during install if you can't show more RAM into it).
