 So using a completely -current kernel, except for the august version
 of sys/dev/cardbus/*?  I wouldn't have expected that to compile, but
 that's a good data point if true.

Yes, it compiled. The only complain was about DETACH_NOWARN.

 : xl0: 3Com 3c656B Fast Etherlink XL port 0x1000-0x107f mem
 : 0x84002000-0x8400207f,0x84002000-0x840020ff irq 11 at device 0.0 on
 : cardbus1 xl0: Ethernet address: 00:50:04:92:29:17

 What does vmstat -i say about irq 11?

This is for the new kernel:

interrupt   total   rate
stray irq0  1  0
stray irq6  1  0
npx0 irq13  1  0
ata0 irq14   1323 12
pccbb1 irq111  0
atkbd0 irq1   200  1
clk irq010417100
Total   11944114

This is for kernel with august cardbus:

interrupt   total   rate
stray irq0  1  0
stray irq6  1  0
npx0 irq13  1  0
ata0 irq14   1371 19
atkbd0 irq1   133  1
clk irq0 6868 99
xl0 irq11  63  0

So its pccbb1 on irq 11 in the first case, and  xl0 in the second.

OK.  I've recreated this problem.  It looks like I broke interrupts to
cardbus with the large cleanup.  I could have sworn I'd tested that,
but it looks like my testing metholology was flawed.  I'm looking into
it.  Thanks.
