I tried to disable regulator at all (so, regulator is left in default state), 
stock bootloader configures CPU to 208mhz(normal)/312mhz(fast) and enables 
fast mode, but leaves fastbus disabled. So I tried fixed 208mhz and 312mhz 
with fastbus bit set - it hangs in random places, even without cpu freq 
transitions... So maybe it's some hw misdesign, but once again - it works 
pretty stable @104-416mhz with fastbus disabled.
