I was just thinking about that, actually. If you're making a custom mobo,
then as long as you can find an ARM SoC tht has PCI-e, you could just apply
an MXM module and plug in an ATI or Nvidia GPU for which we already have
passably working OSS drivers.
Of course, this defeats the purpose of the exercise - who in their right
mind would use a 2W CPU with a 30W+ GPU in a laptop?
*ROTFL*. yyep. the volari z11 is what ended up in the openrd
ultimate, for pretty much these reasons. yes, i've been looking
around for an IC that does 3D graphics at lower power. there are a
couple from broadcomm but broadcomm are a f*****g nightmare to work
with. their attitude can be summarised as "your product will fail,
therefore we are not interested".
it's very interesting that it's been the U.S. companies whose
attitude has been "your product will fail, therefore we do not wish to
be involved". i find this fascinating.

The 10MB/s is _supposed_ to be for worst-case sequential writes. There is,
however, no defined benchmark, and manufacturers are free to do their own
testing. Most fail any sane real-world measurements of the specification.
I'm glad we agree on anything other than SATA being unworkable.
weell, i'm covering all the angles. genesyslogic's ICs are about $1
- $1.50 even in small volumes so it's not as if it'll break the bank
by putting one on the motherboard, in the case where the CPU itself
doesn't have SATA.
