Axe it! See mails from may/june "boot 11.3-BETA1 hangs om armv5". This did not boot on my Sheevaplug. I stopped trying. A new RPI is cheaper than one hour of work on armv5. But it was fun while it worked. :-) Thanks. Regards, Ronald.

Because of this. One is Maverl soc is not right performance on FreeBSD now. Maverl FreeBSD is 10-30 times slow from Linux. I think armv5t support is not complete on FreeBSD. You say armv5t pmap have bug. But my RT1310(armv5t) work well half of year. I try ldd on armv5t one month ago. That is support for armv4 because of that don't know armv4t instruction by default.
