I had to compile sysrq in first, so it is a different kernel now. At least
the kernel data line in /proc/iomem has changed, so I include the new version:
/proc/iomem
===========
00000000-0009efff : System RAM
000a0000-000bffff : Video RAM area
000cc000-000ccfff : Extension ROM
000f0000-000fffff : System ROM
00100000-07ffffff : System RAM
00100000-00263fae : Kernel code
00263faf-002faebf : Kernel data

10000000-10000fff : yenta_socket
10001000-10001fff : 0000:00:0a.1
10001000-10001fff : yenta_socket
10400000-107fffff : PCI CardBus #01
10800000-10bfffff : PCI CardBus #01
10c00000-10ffffff : PCI CardBus #05
11000000-113fffff : PCI CardBus #05

c0000000-c3ffffff : 0000:00:08.0
c0000000-c03fffff : vesafb
After unplugging the card without bringing the interface down manually first
I called /sbin/ifconfig which would not return. The trace shows two instances
of ifconfig, both with STAT 'D'. The first ifconfig originated from the system
attempting to bring the removed interface down:
from /var/log/kern.log
