Still problems with -CURRENT on Dell Inspiron 6000

Some months ago I reported problems with ACPI on a Dell Inspiron 6000
machine running -CURRENT as of the end of November 2005.  The only way
I was able to use the machine at all was to disable ACPI.

In the last couple of days, I've upgrade the machine two ways on two
different partitions:

 - To 6.1-RELEASE.  Here everything seems to work, including ACPI,
   though I'm not sure how to get it to suspend when shutting the lid,
   nor how to recover from zzz(8).  Any suggestions welcome.

 - To the latest 7-CURRENT.  The ACPI problems are there, unchanged.
   In addition, I can no longer use the onboard NIC (bfe0).  When I
   try to ifconfig it, it gets an interrupt storm and drops the
   physical link (the LEDs next to the connector go out, and it
   reports "no carrier").

Here are details of the latter problem:

May  8 11:41:52 eucla kernel: bfe0: <Broadcom BCM4401-B0 Fast Ethernet> mem 0xdfcfe000-0xdfcfffff irq 9 at device 0.0 on pci3
May  8 11:41:52 eucla kernel: miibus0: <MII bus> on bfe0
May  8 11:41:52 eucla kernel: bmtphy0: <BCM4401 10/100baseTX PHY> on miibus0
May  8 11:41:52 eucla kernel: bmtphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
May  8 11:41:52 eucla kernel: bfe0: Ethernet address: 00:12:3f:d8:f3:5c

May  8 11:48:19 eucla kernel: Interrupt storm detected on "irq9:"; throttling interrupt source
May  8 11:48:19 eucla kernel: bfe0: link state changed to DOWN

I have no way of knowing whether this would occur with ACPI loaded.
I've also tried using both the internal iwi0 interface and the
external wi0 interface.  I didn't get an interrupt storm, but I don't
have wireless access round here, so I can't confirm whether the
interfaces work.
