AIX is closed source, non free and proprietary.
Power architecture is indeed open as being backed by a independant organization. However, I doubt the specifications are free to implement without some sort of royalties so it's still proprietary to me.
For an Open Source Initiative compliant CPU architecture (GPL'd), have a look there:

PowerVM Lx86. you can actually load an off the shelf RHEL OS.

Correct

Solaris linux is built into the Sun OS.

Indeed, and that is one of its strenghts as it can benefit some Solaris kernel features not available under the Linux one, like dtrace and ZFS.

Sun Linux Kernal support is only at Red Hat Enterprise 3.

But it is known to run several other Gnu/Linux distributions.

again, the dependency for Sun and SLA with ISV's is something I want to stay away from.

Using PowerVM Lx86 is a more vendor dependant solution in my opinion.

From the books it looks good - once you get under the covers, lots of grey.

Looks fud to me.

if you need L Kenrel 2.6 or greater Sun is not your choice.

Kernel 2.6 support with brandz is a work in progress:

Moreover, LX Branded zones aren't the only solution to run Linux binaries in or along a Solaris environment.
You can run Linux kernel 2.6.23 and newer at native CPU speed (not like Lx86 bytecode translation) with UltraSPARC T based LDoms.
You can run Linux distributions under Xen (xVM).
All of these technologies a freely downloadable, are free for personal, educational and commercial use and are open sourced.
All but LDoms do run on cheap no-name PCs.
The alternative solution you promote is far from that.
Moreover, you'll soon be able to run Linux under VirtualBOX on top of Solaris too. Beta available here:
