No sungem driver in daily netinst image for PowerPC

[Dmitry Ivanov <dimss@telecentrs.lv>]

Hello!

I'm trying to install Squeeze to PowerPC Apple Mac mini. This computer 
needs sungem driver for ethernet card. But there is no sungem driver in 
this image. In fact, there is only one file in 
.../kernel/drivers/net/wan: hdlc.ko. Besides that, installer complains 
that kernel is missing lvm support. Looks like there is something wrong 
with inclusion of modules into installer image. I don't know where to 
start my investigation. Which part of the whole system is responsible 
for building installer images?
