I installed Cacko 1.23rc1 for SL-C3100, everything works fine, except for my compact flash wi-fi card (Planex GW-CF11X), which was working when I was using original Japanese ROM. I hope, using this kernel will solve this problem. On the other hand, some guy from OpenZaurus told, they will not make a ROM for this model, until Sharp releases the source code for the kernel.
