I found that enabling swapfile support in Kconfig also reduces the frequency of OOMs on my sh7760. While I don't experience your particular problem, my personal observation is that since around >2.6.22 linux-sh may OOM without actual swapspace a lot sooner (i.e. post 2.6.25 I can't even do "emerge -pv world" without the kernel OOMing on me! This is with unreviewed platform code, so take this info with a mountain of salt).
