If any replied privately to me between maybe Sat 14:00 & Sun Jun
17 18:10 CEST 2007, please resend as I lost mail (my typo. in .procmailrc).

I did earlier get a private reply from Tuc at Beach House

But there was no next in thread on:
http://docs.freebsd.org/cgi/getmsg.cgi?fetch=20493+0+archive/2007/freebsd-mobile/20070617.freebsd-mobile


I want to make a diff & send-pr it, but advice needed please, what
should one leave on & off for a maximum chance of a slow safe boot
of old legacy hardware.  Please correct my notes extracted from
here, Thanks: http://berklix.org/~jhs/hardware/laptops/#loader.conf

    * hint.kbdmux.0.disabled=1
      Above is referenced by forth/beastie.4th:bootsafekey
    * hw.pci.enable_io_modes=0 # use if boot hangs after AGP
    * hw.pcic.ignore_pci=1 # ignore pci cardbus bridges Dell_Latitude_XPi_P133ST
    * hw.pcic.intr_path="1" # Needed by host=lapa Dell_Latitude_XPi_P133ST
      Normally interrupts for cardbus bridges are routed over the PCI bus (2). \
However, some laptops will hang when using PCI interrupts due to bugs in this code. \
Those bugs can be worked around by forcing ISA interrupts (1). Warner wrote: \
                Libretto-50 and Libretto-70 machines have only ISA PCMCIA bridges
    * hw.pcic.irq="0" # Needed by host=lapa Dell_Latitude_XPi_P133ST
      Override IRQ configured by system for all pcic devices
    * hw.pcic.pd6729_intr_path
      Determine interrupt path or method for Cirrus Logic PD6729 and similar I/O \
space based pcmcia bridge. Chips on a PCI expansion card need a value of 2, while \
chips installed in a laptop need a value of 1 (which is also the default). This is \
similar to hw.pcic.intr_path, but separate so that it can default to ISA when \
                intr_path defaults to PCI.
    * hw.pcic.ti12xx_enable_pci_clock
      Some TI-12xx parts need to have the PCI clock enabled. These designs do not \
provide a clock themselves. Most of the reference boards have the required oscillator \
                parts, so the number of machines that needs this to be set is \
                vanishingly small.
