APM_IOC_GETPOWER ioctl read/write. Setting the batteryid in the passed
structure returns the data for just that battery. The old ioctl
remains for binary compatibility but has been renamed.
Itojun already did the hard work -- I just added a couple of lines.

they keep giving error 0x30b. Unfortunately this keeps happening every second
making the console unusable. Keep track of the last error that occurred and
if the last 10 times apm was called the same error was returned, give up and
exit the apm thread.
finish up incomplete job of moving structure used by bioscall() to
<machine/bioscall.h>, with associated changes in include file strategy,
genassym stuff, etc.
/*
* void bioscall(int function, struct apmregs *regs):
* call the BIOS interrupt "function" from real mode with
* registers as specified in "regs"
* (for the flags, though, only these flags are passed to the BIOS;
* the remainder come from the flags register at the time of the call:
* (PSL_C|PSL_PF|PSL_AF|PSL_Z|PSL_N|PSL_D|PSL_V)
*
* Fills in *regs with registers as returned by BIOS.

Thanks to Charles Hannum for complaining and inspiring me to hack this
together.
