Sort of. The GENERIC kernels contain support for (almost) each and every
hardware supported on this platform. Your kernel will contain a lot of
stuff you never need, like everything that's labeled sun4, sun4c. sun4d
or sun4u - the SS20 is a sun4m machine.

If I remember correctly sparc kernels have problems if they exceed a
certain size ( about 4MB or so but it may be mnore these days ) - have a
look at your kernel config and your dmesg output, then throw out what
you don't need ( device drivers, filesystems, CPU support... ), set
your COPTS environment variable to something like "-mcpu=3Dhypersparc
-mtune=3Dhypersparc -O2" and compile again - this should result in a much
smaller, faster and hopefully more stable kernel.
Just for comparison - my -current SPARCbook 3GX kernel ( a sun4m laptop,
the kernel contains all kinds of fancy and experimental stuff ) is about
2.1MB, yours will probably be smaller.
good luck
Michael
