Subject: [9fans] SATA controller found by kernel but not 9load

i missed this question earlier. sometimes it's straightforward. but
generally it's difficult. there are two reasons for this. first, 9load
doesn't have any procs, tasks or any other multiprogramming constructs.
so sleep and wakeup are out the window. the other reason is that
the problem of writing a boot-loading driver is conceptually different
than writing a kernel driver. performance just isn't an issue. getting
the job done with as few resources as possible is the goal.
