NSLU2-Linux has DSM-G600 revB compatible feed in here:
http://ipkg.nslu2-linux.org/feeds/optware/ts101/cross/unstable/
All files are compiled against uClibc 0.9.27 so this means that some slight incompatibility may happen.
It may be necessary to recompile this feed for 0.9.26 (testing needed)
SNV source is available at here:
http://svn.nslu2-linux.org/svnroot/optware/trunk/
Change platforms/toolchain-ts101.mk CROSS_CONFIGURATION_LIBC_VERSION parameter to 0.9.26
This wiki page and ipkg tool is writing in progress.
