Mine is.  I once tried googling the cubbi kernels, but besides a couple
of discussions about them, I found more information about Care Bears
than Linux Kernels.

My OEM is shipping an ASUS motherboard in their laptop.  I've been told
by them that they require the cubbi_suspend2 stuff in order for some of
my hardware to work correctly, including suspend and hibernate.

Being that this is my first laptop, I'm kinda learning about Linux
Laptops as I go along (but I've been running Linux desktops since Linux
version 0.12).

Any information as to why the cubbi_suspend2 kernels exist and why they
are necessary would be appreciated here.  I assumed (probably
incorrectly) that they were used on most laptops.  Image my surprise
last night to discover the are shunned by people here!

I wasn't sure if I *could* even boot a stock FC kernel and have it run,
or even a vanilla Linux Kernel.  I may give it a try later tonight or
tomorrow night when I have more time.

I'll report back what I find.  Thanks for the kind words.

I will.

My OEM mirrors the mhensler repos themselves.  I'm not sure if they are
even the same that you provide or not.  They also provide kernel modules
for my ATI Mobile Radeon X1600 video (but I haven't seen one for the
2944 kernel yet).  They also provide quite few special installation
scripts for other features such as my ipw3945 wireless, and some general
stuff for expanded video support, software which makes my win-modem
work.  I've installed MythTVfrontend so I can view my recordings on my
laptop if I so choose to.  Unfortunately, the USB webcam doesn't work yet.

I have no clue (yet, I want to learn).  I'm still having a few problems
like my wireless isn't stable (doesn't always connect), and I think I
may have broken something in my video configuration (while fglrx is
installed and mostly works, my fullscreen video is *very* slow).  So
far, the vendor has been unsuccessful in solving these problems, but I
probably broke them the day I received the laptop by installing some of
my favorite repos and doing a couple of "updates" before figuring out
what I broke by doing so.

So, I thought I'd post here about them one at a time as I get them
"fixed".  I thought I'd start with my USB mouse problem.  Big misteak
apparently.  B^)
