The WL500gPv2 is working fine (see [1]).
The WRT54GL is one of the devices, which always had problems with 4.9
(and also 4.4 in trunk with KALLSYMS enabled)

@Hauke: I just did some kind of 'investigation' and probably found a solution
or at least a workaround for me. But as I'm not an expert in CFE and booting,
I have no idea whether (and why) my findings really are the issue's origins.
And if this can be fixed in the loader or must be fixed in the CFE.
Please check out (and maybe also try yourself) what I've documented at [2].

My WRT54GLs are now booting kernel 4.9 :-) 
(Being happy to (still) have 'current trunk' on the good old WRTs)
