: :   Change EISA probing to be less invasive.  Instead of probing all slots
: :   unconditionally, stop after the first one (system board) if no EISA hardware
: :   is detected.  This fixes a boot hang (i.e. Thinkpad) when ACPI is disabled.
: :   Also, split the probe code into a separate function and do some style cleanup.
: :   
: :   Note that the Adaptec 2842 VLB controller probe is broken by this change
: :   and will fail to probe.  It should be fixed separately.
: 
: This change, btw, was reviewed by gibbs and imp prior to the
: commit...  The 2842 VLB controller is about 13 years old.  There will
: likely be a fix for it soon from the ahc maintainer.  However, even if
: there isn't, the belief is that modern laptop owners with the eisa
: hang problem is >> the 2842 controller.  I believe the re@ signed off
