Seeing the log would be interesting, indeed.

Sorry, I personally don't have much experience with bootloaders at
all.  If I had to use one, I'd probably start out with something that
implements STK500v2.

    id               = "m32c1";

Well, please don't append that kind of metadata into the file itself.
Once committed to SVN, your name will be recorded in the commit
message (and in the file ChangeLog as well).

You are apparently using TAB characters in the assumption they were 4
positions per TAB.  Everything else in AVRDUDE uses TABs as 8
positions per TAB.  It's probably best to not use TAB characters
alltogether to avoid that kind of discrepancy.

    desc             = "ATMEGA32C1";
    has_jtag         = no;
    has_debugwire    = yes;
    has_pdi          = no;
    has_tpi          = no;

Basically, only "has_debugwire" needs to be mentioned, as all the
other methods default to "no" anyway.

    stk500_devcode   = 0x82;

Btw., the AVR Studio 4 XML file for this devices mentions 0x66, I just
noticed.

    #avr910_devcode   = 0x74;
    signature        = 0x1e 0x95 0x86;

    pagel            = 0xd7;

OK

    bs2              = 0xa0;

That ought to be 0xE2 (as PE2 is the "BS2" line).

"pagel" and "bs2" are only used by the genuine STK500 in the
high-voltage parallel programming algorithm when running with firmware
version 1.  Not much relevance anymore today.  I guess all STK500s are
running V2 firmware these days, the STK500v1 protocol only survived in
some bootloaders (but they don't deal with parallel programming).

    chip_erase_delay = 9000;

That matches the datasheet, however, the XML file only claims 45 µs.
I'd stay with the 9000 though, to be on the safe side.

    pgm_enable       = "1 0 1 0  1 1 0 0    0 1 0 1  0 0 1 1",
                       "x x x x  x x x x    x x x x  x x x x";

    chip_erase       = "1 0 1 0  1 1 0 0    1 0 0 x  x x x x",
                       "x x x x  x x x x    x x x x  x x x x";

    postdelay           = 1;
    pollmethod          = 0;

According to the XML file, pollmethod should be set to 1.
