In the last time, more and more laptops have problems to 
boot with Linux.

The most frequent problem is that IDE drives are not 
found, or cannot be accessed because reclaimed as ocupied. 
  The only mean to access them and to get it booted, is 
with pci=off.   However, with this, the system becomes 
almost unuseable, lspci also shows nothing.      ITS 
NECESSARY THAT SOMEONE MAKE A KERNEL PARAMETER  pci=noide 
, so that all hardware is registered, with exception of 
ide (and sata) drives   !!!!   This problem, for example, 
also happens on IBM/Lenovo Thinkpad laptops.

A Toshibe Satelite laptop, I need go back to kernel 2.6.23 
. With later kernels, at the beginning of the boot the 
screen become black and nothing more happened.  The same 
happens on that laptop with all newer Slackware kernels

I'm not sure it is not.

No, it doesn't.

Care to send .config from your kernel?

Some detailed diagnostic information would be useful.

First reporting point for distro kernels is the distribution. Do modern
non-Slackware kernels (eg Fedora, SuSE) work on the problem laptop ?

i run on thinkpad r61 . i have experienced no problems.
what specific model are you running into trouble and with what
specific kernel-configuration? 

maybe this helps: http://tuxmobil.org/ibm.html

did you try any recent fedora/ubuntu/debian live-dvds? this is normally
the easiest way to check if there is a real problem or if it is only a
kernel-configuration issue.
