Together with the bug submitter we tried to debug this issue further.
I've build a modified netboot image, which contained a 2.6.17 kernel
with some extra debugging output in the PCI probing code. The relevant
part of the function pci_read_bases() in drivers/pci/probe.c which
actually gets the memory regions from the card looked like that:
static void pci_read_bases(struct pci_dev *dev, unsigned int howmany,
int rom)
{
unsigned int pos, reg, next;
u32 l, sz;
struct resource *res;
for(pos=0; pos<howmany; pos = next) {
next = pos+1;
res = &dev->resource[pos];
res->name = pci_name(dev);
reg = PCI_BASE_ADDRESS_0 + (pos << 2);
pci_read_config_dword(dev, reg, &l);
pr_debug("pci_read_bases: device %s, pos=%u, got l=%lx\n",
pci_name(dev), pos, (unsigned long) l);
pci_write_config_dword(dev, reg, ~0);
pci_read_config_dword(dev, reg, &sz);
pr_debug("pci_read_bases: device %s, pos=%u, got sz=%lx\n",
pci_name(dev), pos, (unsigned long) sz);
pci_write_config_dword(dev, reg, l);
if (!sz || sz == 0xffffffff)
continue;
if (l == 0xffffffff)
l = 0;
if ((l & PCI_BASE_ADDRESS_SPACE) == PCI_BASE_ADDRESS_SPACE_MEMORY) {
sz = pci_size(l, sz, (u32)PCI_BASE_ADDRESS_MEM_MASK);
pr_debug(" memory: device %s, pos=%u, sz=%lx\n",
pci_name(dev), pos, (unsigned long) sz);
if (!sz)
continue;
res->start = l & PCI_BASE_ADDRESS_MEM_MASK;
res->flags |= l & ~PCI_BASE_ADDRESS_MEM_MASK;
pr_debug(" memory: device %s, pos=%u, start=%lx, flags=%lx\n", pc
i_name(dev), pos, (unsigned long) res->start, (unsigned long) res->flags);
For the cassini cards the dmesg output looked like that:

So the first card returned nothing but zeroes, and the second one
produces the values, which cause pci_size() to return zero, and again
we get nothing useful. Do this cards require some special treatment
before they can be properly initialized by the PCI subsystem?
I am also attaching the complete dmesg output to this message.
