hmm, I could install it but my config doesn't work.
I have a root system on the SD and this config line:
g GENTOO sd IMAGE
or
g GENTOO sd $IMAGE
or
g GENTOO sd
Although there is the bootmenu and I can type in g, it just starts the normal internal ROM.
If there is an error message, I cannot see it because this damn gpe-splashscreen appears.
