Try increasing the default size of the ramdisk in the kernel's config.

Perhaps we need a nice --help?

I would bet this is due to the kernel config, as stated above.

cd /opt/pxes-1.0/stock/arch/i586/modules/lib/modules/2.6.10-2pxes.2
(or whatever your kernel directory happens to be based on your custom
kernel image)

I use the following script, called modules-create, from within this
directory.

#!/bin/bash
MODDIR=3D"../../../tmp"

for i in modules.dep modules.generic_string modules.ieee1394map
modules.isapnpmap modules.parportmap modules.pcimap modules.pnpbiosmap
modules.usbmap
do
        rm $i
        ln -sf $MODDIR/$i $i
done

The main thing is that these files are symlinks to the /tmp directory on
the image, as PXES generates these files at boot.
