To my understanding it is not possible to be bought as 2Ghz chip, because all chips ever manufactured were 1.8Ghz parts (run also at 2Ghz, though, but only as overclocked a little).
(you could sue those marketing those 2Ghz chips perhaps)

I try.

Supported as well as existing OS can do it.
(Second core is not supported by AOS4 as AOS4 is not capable to do SMP yet. And IIRC, GCC for AOS4 does not yet fully optimize for PA6T.)

All supported.

I think they are supported.

Supported in some ways (similarly as the FPGA of SAM?)
So far no developer has done anything signifficant with it and one can not blame a-eon for that I think.
Other supported/in use things are:
Onboard SATA2(not perfectly IIRC), audio,
GPU is poorly supported, only in 2D+compositing when AOS4 is used.
There is no 3D driver for modern GPUs on PPC amigalikes.
Not sure if onboard PATA is supported.
Anyway, it would be nice to see the lest of the another half of HW features that are not supported.

LOL!
Btw PA6T has huge DSP performance via Altivec. And xena can do DSP functions also (just inferior when compared to Altivec capabilities).
xena is a bridge chip. One can use it to do things like bridge to A1200 trapdoor connector (like original eyetech/AInc idea was). (I'm sure no one will do that bridge) Another example would be to bridge legacy ports via xena and the available xorro prototyping board.
>> and adding more Xena cores (how when Xorro isn`t it? Via USB? PCI?)
To my understanding xcore links are available on the xorro slot. One should be able to add matrix of xcore chips there.
and...

As long as AOS4 SW is not capable of using multiple cores, but capable of using Altivec of PA6T, Cyrus is not much faster.
>Sadly its again two versions of Cyrus with CPU soldered instead of one board with changeable CPU.
I think that would require a CPU card. And it would make Cyrus more expensive.
And there is three cyrus versions in the plans. x3500, x5000/20 and x5000/40.
(I think they should forget the x3500, though ... unless they manage to come close to SAM460 price)
IMO: x1000 is great HW. Only too expensive for me and for (too) many others.
