Not the case for Sparc64. And on older 32 bit sparc systems, the size
limit was about 2.6MB

Your distribution should have come with a tool called prtconf. This will
list the OBP tree for you (it's a port of the solaris version of the
command). In order for the command to work, though, you need to have the
device /dev/openprom. This is an option in the Kernel. 

So, without having to worry about size limitations, this is not really a
critical issue. but if you want to slim the kernel down anyway, compile
a larger kernel for now that includes /dev/openprom and then use prtconf
to figure out what you need / don't need for your next compile. 

There is also an eeprom command (/usr/sbin/eeprom) which should provide
you with similar info ...

Then to save you some more disk space (if you are concerned about that,
too), you can gzip -9 your kernel, and SILO will decompress it itself at
boot time (just takes a couple extra seconds to boot the box).
