This happened after a switch from 2.6.15 to 2.6.16. I think the reasons
might be in the I2C module that has been changed.
In the 2.6.15 it was I2C_KEYWEST while in 2.6.16 it is named
I2C_POWERMAC.
Wrote an email to the author of the pbbuttons but had no reply. It
would
be great if we can sort out the problem in this list.

Hi there,
I'm not sure if this will be of help... I have an older model G4 ibook
(with a G3 proc) which does not have the lighted keyboard feature...
check to make sure you have event interface enabled (the EVDEV module)
in your kernel. Also enable APM emulation or something like that under
the new Mac drivers menu.
I've also noticed that the pbbuttonsd.conf default kbd light value is
0, maybe that needs a different value? Have you tried changing the
light sensor threshold values as well? also running pbbcmds? any luck
with that?
I dunno...hope this was somewhat helpful...
best,
alden
Thanks for the suggestion - EVDEV is enabled as part of the kernel.
apm_emu is loading as a module. My pbbuttonsd.conf has the kbd
illumination value is set to 0 but it is also commented out.
Since I was looking at my kernel config I went ahead made 2 changes
compiled a new kernel to test.
old kernel (per the .config file):
i2c support
config_i2c=y
config_i2c_chardev=y
i2c algorithms
config_i2c_algobit=y
config_i2c_algopcf is not set
config_i2c_algopca is not set
i2c hardware bus support
...
config_i2c_powermac=y
...
misc. i2c chip support
...
(nothing is configured here)
new kewrel (per the new .config file):
i2c support
config_i2c=y
config_i2c_chardev=y
i2c algorithms
config_i2c_algobit=y
config_i2c_algopcf is not set
config_i2c_algopca is not set
i2c hardware bus support
...
config_i2c_powermac=y
...
miscellaneous i2c chip support
...
config_i2c_debug_core=y
config_i2c_debug_algo is not set
config_i2c_debug_bus=y
The result, my syslog is filling up w/ hundreds of lines detailing the
i2c devices loaded the keyboard now lights up. When I boot back to
the old kernel (the one without the debug_core debug_bus enabled) it
stops working. lcd brightness works on both of them works on both. I
ran a diff on the 2 .config files and verified that there were no
changes other than what I just documented.
my confusion has just increased
Eric
