I believe you can override the error member of the pci_access struct
to do what you want and it won't exit on you. In Mike's patch, it
does:

        pacc = pci_alloc();
        pci_init(pacc);

So, you'd just have to set pacc->error to something more sensible for
hal. The default is this:

static void
pci_generic_error(char *msg, ...)
{
  va_list args;

  va_start(args, msg);
  fputs("pcilib: ", stderr);
  vfprintf(stderr, msg, args);
  fputc('\n', stderr);
  exit(1);
