SUMMARY: sol2.6 /dev/ksyms woes?

The problem was solved by adding this entry to /etc/system:

set kobj_map_space_len=0x300000

On Solaris 2.6, the space set aside in memory for kernel objects (such 
as drivers) is a fixed size.  The more objects you have mapped, the more 
space you may need.  This increases the size 3 fold.

In Solaris 7 and beyond, kernel object space is dynamically allocated.
