NetBSD/sparc under qemu ?

[Manuel Bouyer <bouyer%antioche.eu.org@localhost>]

Hi,
did anyone have success running NetBSD/sparc under qemu (or other emulator) ?
I have an aging SS10 still in production, for which qemu would
be a good remplacement (it has to run NetBSD/sparc as it runs
some SunOS 4 binaries). A NetBSD 2.0 kernel (this is whats runs on the SS10
at this time) fails with:
Kernelized RAIDframe activated
