Ok, works for "ves1820_init", but sorry for stupid question:

How to get this number in "ves1820_init" which has only structure "fe"
available.

First: I'm not so familiar with this driver, second it's easy for testing
if such parameters can be supplied by module option, third: no rewrite of
start scripts required, only add options in /etc/modules.conf like

EXAMPLE, currently not supported by module (only private patch):
options ves1820 clkconf=0x12,0x12 carconf=0x12,0x12 pwm=0x38,-1
