5.2.1 on Acer Travelmate 800 LCi boot of install CD fails

[Clint Gilders]

This is a 5.2.1 mini install ISO downloaded today.  The Laptop is a 1.3 
Ghz Centrino with 30GB drive, broadcom Ethernet, Intel 2100 Mini PCI 
wlan, 30Gb drive, ATI Mobilty Radeon 9000 graphics.

When I select the default boot:

It goes through much of the hardware detection and freezes at:

Timecounters tick every 10.000 msec
ata0-master: WARNING - ATA_IDENTIFY interrupt was seen but taskqueue 
stalled LBA=0

With ACPI disabled it is much the same with a few more errors before it 
hangs:

unknown: <PNP0303> can't assign resources (port)
unknown: <PNP0f13> can't assign resources (irq)
unknown: <PNP0501> can't assign resources (port)
fdc1: cannot reserve I/O port range (1 ports)
unknown: <PNP0401> can't assign resources (port)
unknown: <HWPc224> can't assign resources (port)

Timecounters tick every 10.000 msec
ata0-master: WARNING - ATA_IDENTIFY interrupt was seen but taskqueue 
stalled LBA=0

In safe mode I get the same errors as above.

With verbose logging I get:

Timecounters tick every 10.000 msec
lo0: bpf attached
ata1: spurious interrupt - status=0x00 error=0x01

Varous Linux Distros work fine on this Laptop, and so does FreeBSD 4.9.

Ideas?  Solutions?  Thoughts?   Any other info I could provide to help 
fix this?

Thanks
