I think, "make install" runs mkinitrd. Just type mkinitrd to see how to use
it directly.

A few days ago, I built and booted a kernel from Geoffs git tree on a
freshly installed F8.

The problem seems to be that the F8 mkinitrd expects certain modules to be
available (ehci-hcd, ohci-hcd, uhci-hcd, ps3rom, ps3rom), probably because
the F8 kernel is built that way. Some of them are compiled into the kernel,
some are not compiled at all when you start with "make ps3_defconfig".

So, the obvious solution is to just configure those device drivers as
modules in .config. However, it is a bit more tricky, because uhci-hcd
(USB_UHCI_HCD) depends on CONFIG_PCI, which is not set in ps3_defconfig. So
make sure you enable that first, before looking for USB_UHCI_HCD.
