Try using the latest xfsprogs (or at least 2.9.x), lots of
improvements have been made to the memory usage. It may not be of much
help though, you really should be running a 64-bit kernel.

32-bit kernel is limited to ~4GB of memory per process. 64-bit is not.

The amount of memory xfs_repair requires depends on the filesystem
characteristics (how many inodes, etc etc)
