The lircd process runs as root -- so it has access to everything. I'm
assuming that rtc support is built in and working, since this works:
root at myth-fe:/proc# cat /proc/driver/rtc
rtc_time : 18:35:26
rtc_date : 2007-04-27
rtc_epoch : 1900
alarm : 00:00:20
DST_enable : no
BCD : yes
24hr : yes
square_wave : no
alarm_IRQ : no
update_IRQ : no
periodic_IRQ : yes
periodic_freq : 1024
batt_status : okay
Anything else I should check?
