Since you have the same name as me, I'll reply :)

What you are probably seeing is the fact that I believe that the load 
average is not measuring the same thing on Solaris and Linux. On Linux, it 
includes processes in uninterruptible sleep (eg disk I/O), and on Solaris 
it does not. It is reasonable for the value to be higher on Linux. Whether 
or not either method of calculation is more reasonable is of course a 
different question.
