As I will probably only have one chance to fix this (without having to get the
ISP's help again) I was wondering if there are any clear instructions on how to
remove a failed kernel RPM update, returning the server to the state it was in

If you do not want to involve the ISP ever again when a kernel won't
boot, you can configure a fallback kernel [0]. I've used something
similar a very long time ago when the main boot loader was LILO - it was
much easier to do this kind of thing with it.
