Greetings,
W.r.t kernel - 2.6.38.8
This page http://www.xenomai.org/documentation/xenomai-2.6/TROUBLESHOOTING
asks us to disable "CONFIG_CPU_FREQ".
Power management and ACPI options
-->CPU Frequency scaling
-->-->CPU_FREQ_GOV_CONSERVATIVE
-->-->CPU_FREQ_GOV_ONDEMAND
-->-->CPU_FREQ_PMAC64
-->-->CPU_FREQ_DEFAULT_GOV_PERFORMANCE
-->-->CPU_FREQ_GOV_PERFORMANCE
-->-->CPU_FREQ_GOV_USERSPACE
There isn't any particular option named "CONFIG_CPU_FREQ".
Does this mean that we have to disable whole bunch of all these above options?
Same is the case with "CONFIG_APM". It also has various variants as follows:
APM_CPU_IDLE
APM_IGNORE_USER_SUSPEND
APM_DO_ENABLE
Location is said to be in:
--> Power management and ACPI options
-->--> APM (Advanced Power Management) BIOS support (APM [=n])
But in kernel 2.6.38.8 there isn't any option called "APM (Advanced
Power Management) BIOS support" anywhere.
"Power management and ACPI options" results in the following menu.
[*] Power Management support
[*] Power Management Debug Support
[*] Extra PM attributes in sysfs for low-level debugging/testing
[ ] Verbose Power Management debugging
[*] Suspend/resume event tracing
[*] Suspend to RAM and standby
[ ] Test suspend/resume and wakealarm during bootup

Has some names been changed or I am simply missing some point?
Please guide.

No, all the options are still there in linux 2.6.38.8. I am a bit
surprised that given the time you have spent been asking questions on
this list you still have not built and run Xenomai.
The real hard part of the job using Xenomai is to start writing
applications using it and debugging them, not installing, compiling and
configuring it.

Forgot that:
$ find linux -name '*Kconfig*' | xargs grep 'config \(APM$\|CPU_FREQ$\|ACPI_PROCESSOR$\)'
linux/drivers/cpufreq/Kconfig:config CPU_FREQ
linux/drivers/acpi/Kconfig:config ACPI_PROCESSOR
linux/arch/x86/Kconfig:menuconfig APM

The GUI has a "research" function. I believe in make menuconfig it is
the '/' character.

The Kconfig are the data used by make menuconfig to build the menu. You
do not want to modify them.
This said, this list may not be the best place to ask questions about
configuration/compilation of the Linux kernel.
Please no private mails.

Deep apologies for the "private" mail. To be honest that was NOT the
intention at all.
I use Gmail. So, I forgot to click "reply all". I clicked "reply".
That made the difference.

I did send the mail "after" using the "/" function. And no APM it is
still not there.
I have already created a thread on the LinuxQuestions.org, hope it'll
get solved.
They said I need to enable some options in the .config file.

Thanks for the information. Yes, now I remember.
