This laptop is mentioned in the HCL.
Any kernel can be customised however you want. You should get the latest 2.4.* or latest 2.6* kernel, and configure them to your requirements.
Sometimes there are laptop specific things not in the default kernel in your distribution, such as PCMCIA support, APM, ACPI, etc. Plus you might want to patch the kernel with supermount, bootsplash, some driver for non-standard hardware, etc. Although you probably don't need
to compile your own kernel, it is not really that difficult if you have some patience and are prepared to do some reading/learning.
Important: Don't delete your old one, in case you forget to enable something important which stops your system booting.
If you keep your old kernel, you can always go back to how it was before you messed it up
. I always forget something!
Make sure your read a Kernel HOWTO before you start.
