LBA48 support for Linux 2.4.18

Support for LBA48 in Linux I think got introduced in 2.4.19, so if you are forced to use 2.4.18 as I am, then you need to apply a patch. This is needed to access the whole capacity of IDE disks over 137.4 GB.
I have a kernel source tree which has this patch along with patches to support using the Speedtouch ADSL PCI modem. This modem uses an ITEX Apollo chipset, and the only driver is a binary one from ITEX (which wen bust I think) which will not work on a later kernel.

The patch itself is available around the internet and also here.
