The `4c' miniroot is for both sun4c and sun4m machines. Separate
`4' and `4c/4m' miniroots are also no longer necessary in -current.

Can you send me the lines that identify the CPU and cache on your LX?
These are among the first messages printed when the kernel boots.

It might be worth the try to grab a more or less current miniroot
that can be found in ftp.netbsd.org:~ftp/pub/NetBSD/arch/sparc/snapshot.
