FYI - I am not using Linux MintPPC, but I thought that my experience may be of help here.
I recently installed Debian Wheezy onto a Blueberry iBook for my son. I had issues with the ever popular
hermes @ 00019080: Card removed while issuing command 0x0021
In my quest for internet without a wire, I tried some ideas found on this board. Nothing seemed to work. The anwser for me was to disable wicd and set up manualy.
iface eth1 inet dhcp
pre-up iwconfig $IFACE essid "your ap essid"
pre-up iwconfig $IFACE key "your key in hex here"
But, while getting here, I found something else interesting. I am now running agere_sta_fw.bin 9.52 on my box. There is a way to retrieve this for use by orinoco_cs module. (This binary resides on my 10.4.11 dual-usb ibook, copy AppleAirPort.kext from your OSX box to a usb key and transer to linux box.) See the following URL for info.http://repo.or.cz/w/agere_fw_utils.git/tree/
You can get 9.48 firmware here (use "raw"):http://git.kernel.org/?p=linux/kernel/g ... git;a=tree
You should check the firmware header to verify that it is not corrupted.
>> Can you confirm the following:
>> * first 128 bytes of your firmware image:

I am happy to see so many people interested in running GNU/Linux on their older ppc machines. Even though I am using pure Debian currently, I thought that my findings would be more useful here.
