A frequent recommendation I see is to remove VESA support from your
kernel, apparently it has suspend/resume issues. I don't think
FreeBSD-10.1 uses the KMS graphics drivers by default, and I /thought/
the recommendation was for KMS systems. Shouldn't hurt to build a
kernel without 'options VESA' and see what happens...
