Yes, indeed. I tried last time on Fiasco.OC, to see the log mesages on 
the screen. So,
it looks like Fiasco.OC is unsupported for Sculpt, or is it possible to 
go further on it
without a fatal error because of missing platform_info? (Maybe, just 
catch this
exception). Yes, now I tried Scuplt on both "hw" and NOVA kernels, it 
works fine on both.
Though, trying to run "sculpt_test" on NOVA in QEMU, I see "drivers" and 
and "runtime" starting, and then silence (no progress). I commented the 
routing rules
in all three subsystems out, so that, now I see all messages in core 
log. Where could
I look more to see why it doesn't start? I see Nitpicker started, but no 
on the screen. No errors. Maybe, I need to wait more, but much time passed.

So, currently Sculpt works with NOVA or "hw" kernels, because core generate

this "platform_info" module. On Fiasco.OC it's missing, so it won't 
work? -- I thought,

it will work on any x86 kernel, excepl Linux... (at least, I see such 
limitation in the

beginning of script).
