Judging on a FREQ value (about 125) from the boot logs, the BIOS had set
up PLL to 50 MHz (125/192 ~ 32/50) which should have "spoilt" the value in the
f_CNT register. Hence, we may guess that the BIOS had saved the f_CNT value
beforehand. If not, there's not much we can do except to guess at the DPLL
frequence that BIOS might have set.
