Kernel question

[Bryan Maynard]

I read through your kernel - very nice comments, thanks a lot!

I compiled the kernel and boot-up is noticably faster, thanks again!

I would like to investigate transfering all the device info from boot -v to 
LATITUDE_C600.hints. I don't really know what most of the info from boot -v
means, I'd like to work on figuring it out. Maybe you could help me learn and we could
figure it out together?

Any help you could give you be greatly appreciated!

One thing of note: I don't have any sound. I've never had sound, but after booting
with the new kernel I went into KDE's control panel and tested the sound system, but
nothing came out. I didn't get any errors when it restarted the sound system so I'm
not sure what's up.

I've incuded the dmesg output from the new kernel boot in case you need to look at it
along with my current CUSTOM.hints file (maybe it'll help. . . :-?)

Anyway, thanks a lot for the new kernel, it works like a charm!

 Do this with the kernel .hints file. it will be statically compile
 into the kernel then.
 kernel.hints = statically compiled = faster boot.
 device.hints = dynamic-ish = slower, but still faster then random probing.

 I've attached a kernel for you to use. Compare it to yours (and
 GENERIC) and read the comments I made in it. It should address most of
 your questions.

 You can put the boot -v info into the kernel .hints file, I think. I
 never tried to do anything like that and I'm not sure how to go about
 doing it. Or maybe thats what kenv is for... hmmm
