It would be helpful to know which SPARC it is that you have. This is a
memory alignment problem... this one is in the kernel.

This, too is a memory alignment issue (well, usually)... you get a Sig10
(aka SIGBUS) when a userspace app isn't memory aligned. The SPARC
architecture has very strict memory alignment restrictions.

Again, knowing which SPARC would be helpful, but it's odd that X doesn't
have the same issues with 2.2.17 or 2.4.x that it does with 2.2.19... at
least from my perspective at the moment.
