That's actually a good point.
Looking at the code,
/* TODO: we are too slack to do reg dumping for pio, for now */
#ifdef CONFIG_8139TOO_PIO
#define rtl8139_get_regs_len NULL
#define rtl8139_get_regs NULL
I seem to recall that I didn't implement it precisely because some
registers wanted to read only at certain bit widths.
