The tiny patch I had done merely handled one part of the problem - of caches.. There are possibly more opportunities such as: i) Organization of ARM code to make it cleanly pluggable and add further features. ii) Optimizations where possible -> bitops etc.. iii) Compiler optimizations and improvements of Makefile b) Beagle is not the only OMAP3 board around.. There is Zoom MDK, SDP3430, Pandora and many more -> A8 support is just the tip of the iceberg in terms of opportunities.
By the way, U-boot v2 has two platforms with OMAP3 -> SDP3430 and beagle - both have A8 on them. Speaking specifically about OMAP3 with A8 and beagle support for u-boot v1, Sakoman, Dirk among others have been working on a git branch[1] which could finally move in to mainline tree in the future.. If you are specifically interested in playing/developing with beagle with CortexA8 on a OMAP3530, - just checkout beagleboard.org - if nothing, just the cost might surprise you.
