from http://mbus.sunhelp.org/modules/index.htm#2.1 :
"Maximum of 1 such module per MBus: these modules did not properly
adhere to the MBus Level 2 (multiprocessor) protocol."

This was about SM40s though, according to the site SM50s may be fine.

from http://faqaboss.sunhelp.org/new/arch.html :
"The following combinations probably work but are unsupported:
    * 2 x SM50 (...)"

So, "probably".
