Hmmm, the above looks like the header for the 8129 driver, except that
it says rtl8139.  Make sure you're using drivers/net/8139too.c   I see
this in the driver:   #define RTL8139_VERSION "0.9.10". I'm using test9
kernel, I doubt that you're driver is out of date -- it seems you're
perhaps using the wrong driver.

Regarding the I/O vs MEM accesses, look for this:


/* define to 1 to enable PIO instead of MMIO */
#undef USE_IO_OPS
