Blame the hardware designers... and give me my big allocations. :)

Sounds drivers (not mine though, <g>) do stuff like

order = 20; /* just a made-up high number*/
while ((order-- > 0) && (mem == NULL)) {
mem = __get_free_pages (GFP_KERNEL, order);
/* use sound buffer 'mem' */

Older or modern, less-than-cool framegrabbers need tons of contiguous
memory too...
