Yes. It needs them for registers (and maybe on-card memory) mappings from the PCI bus into virtual memory. > Starting with 112M and having just ~4M free it seems reasonable that > loading the driver fails. Yup. > I added vmalloc=256M (less didn't work) vmalloc space is used for PCI MMIO mappings, mapping physical pages for loadable modules, and perhaps other allocations of physical memory.
