Hrm, how can I run memtest when I can't even allocate all the RAM without c=
rashing, surely memtest can't allocate all 128 MB of it when it's not avail=
able from the kernel (hence malloc() won't do)...
But that really isn't the issue, because I _don't_ think (IMHO) that a litt=
le bad RAM will cause a kernel panic such as this.
