Whenever I do a clean boot of iMac, it says Kernel_task is taking around 150MB RAM, is that normal?
Yes, as kernel_task is a very important process and 150 MB is not that much.
How much kernel_task is your iMac taking?
I am using Snow Leopard and have seen it take 90 to 500 MB on my Macs. You probably have 4 or more GB of RAM, thus 150 MB should be worrying you.
On my old MBP/Lion with multiple apps open, my kernel_task is using 182MB. For me, Firefox is the biggest hog at almost 500MB.
