I have been able to compile an 8139too PIO module and remove the two sdhci modules and get it to boot Puppy431 which gives me Lan access but no card reader.
There is a kernel patch for this problem, H12Y mmio patch, available at http://bugzilla.kernel.org/show_bug.cgi?id=10231. I have applied the patch and it indicates success but it has not cured either problem.
I'm hoping someone can explain to me where this correction should be applied in kernel 2.6.30.5 in order to be successful.
