thanks Joel, but that didn't work, I got the same error on reboot
I've gone through and deleted all the vanilla kernel directories and
will try to insert modules again as Hans suggested, if that doesn't work
I'll try the initrd path

Firstly thanks to Asbjørn, Lee, Tim and others who have given me advice
so far.
I tried using Asbjørn's vanilla kernel but it didn't work as our laptops
are different, but your config settings were a good guide.
I downloaded the source package for 2.6.16
I did make oldconfig, to use the config already working on my machine
(just without the VXpocket support), I tried compiling the kernel as per
the instructions on the Demudi page
<http://demudi.agnula.org/wiki/Low-latencyKernelBuildingHowto>, and by
referencing Asbjørn's config settings
Lee had written that CONFIG_ISAPNP must be enabled, but this wasn't an
option that I could choose in menuconfig, there was just a hyphen beside
this option, also this wasn't enabled in Asbjørn's settings which
reportedly works.
but got this error message on reboot
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)
I assume this means I didn't have the exact settings configured for my
laptop.

Your problem is that stock kernels usually use an initrd, but when you
compile by hand you aren't setting up the initrd. You can either grok
initrd, or compile a few more things into the kernel instead of as
modules. Needless to say the latter is by far easier.
That is a judgement call.
For the former (under debian, not guaranteed, an example)
apt-get initrd-tools
mkinitrd -o /boot/initrd-img-2.6.16 2.6.16
Add an initrd line to GRUB or LILO
For the latter (ditto, guaranteed not to work)

Here is a start, all the items containing EXT2, EXT3, IDE
but not VIDEO.
Just change all the 'm' or 'not set' to 'y', append to
the end of .config, and compile. (Praying doesn't help,
but it might make you feel better. Pizza and beer are
also considered highly effective.)
